The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5480 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation,     denial of service or information leaks. CVE-2022-4269 William Zhao discovered that a flaw in the Traffic     Control (TC) subsystem when using a specific networking configuration (redirecting egress packets to     ingress using TC action mirred), may allow a local unprivileged user to cause a denial of service     (triggering a CPU soft lockup). CVE-2022-39189 Jann Horn discovered that TLB flush operations are     mishandled in the KVM subsystem in certain KVM_VCPU_PREEMPTED situations, which may allow an unprivileged     guest user to compromise the guest kernel. CVE-2023-1206 It was discovered that the networking stack     permits attackers to force hash collisions in the IPv6 connection lookup table, which may result in denial     of service (significant increase in the cost of lookups, increased CPU utilization). CVE-2023-1380 Jisoo     Jang reported a heap out-of-bounds read in the brcmfmac Wi-Fi driver. On systems using this driver, a     local user could exploit this to read sensitive information or to cause a denial of service. CVE-2023-2002     Ruiahn Li reported an incorrect permissions check in the Bluetooth subsystem. A local user could exploit     this to reconfigure local Bluetooth interfaces, resulting in information leaks, spoofing, or denial of     service (loss of connection). CVE-2023-2007 Lucas Leong and Reno Robert discovered a time-of-check-to-     time-of-use flaw in the dpt_i2o SCSI controller driver. A local user with access to a SCSI device using     this driver could exploit this for privilege escalation. This flaw has been mitigated by removing support     for the I2OUSRCMD operation. CVE-2023-2124 Kyle Zeng, Akshay Ajayan and Fish Wang discovered that missing     metadata validation may result in denial of service or potential privilege escalation if a corrupted XFS     disk image is mounted. CVE-2023-2269 Zheng Zhang reported that improper handling of locking in the device     mapper implementation may result in denial of service. CVE-2023-2898 It was discovered that missing     sanitising in the f2fs file system may result in denial of service if a malformed file system is accessed.
    CVE-2023-3090 It was discovered that missing initialization in ipvlan networking may lead to an out-of-     bounds write vulnerability, resulting in denial of service or potentially the execution of arbitrary code.
    CVE-2023-3111 The TOTE Robot tool found a flaw in the Btrfs filesystem driver that can lead to a use-     after-free. It's unclear whether an unprivileged user can exploit this. CVE-2023-3212 Yang Lan discovered     that missing validation in the GFS2 filesystem could result in denial of service via a NULL pointer     dereference when mounting a malformed GFS2 filesystem. CVE-2023-3268 It was discovered that an out-of-     bounds memory access in relayfs could result in denial of service or an information leak. CVE-2023-3338     Davide Ornaghi discovered a flaw in the DECnet protocol implementation which could lead to a null pointer     dereference or use-after-free. A local user can exploit this to cause a denial of service (crash or memory     corruption) and probably for privilege escalation. This flaw has been mitigated by removing the DECnet     protocol implementation. CVE-2023-3389 Querijn Voet discovered a use-after-free in the io_uring subsystem,     which may result in denial of service or privilege escalation. CVE-2023-3611 It was discovered that an     out-of-bounds write in the traffic control subsystem for the Quick Fair Queueing scheduler (QFQ) may     result in denial of service or privilege escalation. CVE-2023-3609, CVE-2023-3776, CVE-2023-4128 It was     discovered that a use-after-free in the cls_fw, cls_u32, cls_route and network classifiers may result in     denial of service or potential local privilege escalation. CVE-2023-3863 It was discovered that a use-     after-free in the NFC implementation may result in denial of service, an information leak or potential     local privilege escalation. CVE-2023-4004 It was discovered that a use-after-free in Netfilter's     implementation of PIPAPO (PIle PAcket POlicies) may result in denial of service or potential local     privilege escalation for a user with the CAP_NET_ADMIN capability in any user or network namespace.
    CVE-2023-4132 A use-after-free in the driver for Siano SMS1xxx based MDTV receivers may result in local     denial of service. CVE-2023-4147 Kevin Rich discovered a use-after-free in Netfilter when adding a rule     with NFTA_RULE_CHAIN_ID, which may result in local privilege escalation for a user with the CAP_NET_ADMIN     capability in any user or network namespace. CVE-2023-4194 A type confusion in the implementation of     TUN/TAP network devices may allow a local user to bypass network filters. CVE-2023-4273 Maxim Suhanov     discovered a stack overflow in the exFAT driver, which may result in local denial of service via a     malformed file system. CVE-2023-20588 Jana Hofmann, Emanuele Vannacci, Cedric Fournet, Boris Koepf and     Oleksii Oleksenko discovered that on some AMD CPUs with the Zen1 micro architecture an integer division by     zero may leave stale quotient data from a previous division, resulting in a potential leak of sensitive     data. CVE-2023-21255 A use-after-free was discovered in the Android binder driver, which may result in     local privilege escalation on systems where the binder driver is loaded. CVE-2023-21400 Ye Zhang and     Nicolas Wu discovered a double-free in the io_uring subsystem, which may result in denial of service or     privilege escalation. CVE-2023-31084 It was discovered that the DVB Core driver does not properly handle     locking of certain events, allowing a local user to cause a denial of service. CVE-2023-34319 Ross     Lagerwall discovered a buffer overrun in Xen's netback driver which may allow a Xen guest to cause denial     of service to the virtualisation host by sending malformed packets. CVE-2023-35788 Hangyu Hua discovered     that an off-by-one in the Flower traffic classifier may result in local denial of service or the execution     of privilege escalation. CVE-2023-40283 A use-after-free was discovered in Bluetooth L2CAP socket     handling. For the oldstable distribution (bullseye), these problems have been fixed in version 5.10.191-1.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a     .disconnect versus dvb_device_open race condition that leads to a use-after-free.(CVE-2022-45886)

    In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This     could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.(CVE-2023-21255)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in     the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend     upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795.(CVE-2023-3610)

    An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.(CVE-2023-3611)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. This flaw allows an attacker with local user access to cause a system crash or leak internal     kernel information.(CVE-2023-3567)

    Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace.(CVE-2023-35001)

    Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()`     failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network     namespace.(CVE-2023-31248)

    bpf: Fix incorrect verifier pruning due to missing register precision taints(CVE-2023-2163)

    A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local     privilege escalation.Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a     hrtimer.We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59     (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and0e388fce7aec40992eadee654193cad345d62663     for 5.15 stable).(CVE-2023-3389)

    A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c.Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue.We recommend upgrading past     commit1240eb93f0616b21c675416516ff3d74798fdc97.(CVE-2023-3390)

    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in     drivers/media/pci/saa7134/saa7134-core.c.(CVE-2023-35823)

    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c.(CVE-2023-35824)

    A race condition was found in the Philips SAA7134 driver in the Linux kernel. In saa7134_initdev, dev-     video_q.timeout is eventually bound to saa7134_buffer_timeout. If we remove the module or device which     will call saa7134_finidev to cleanup, there may be unfinished work. This could lead to a use-after-free     issue.(CVE-2023-3327)

    An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information.(CVE-2023-3268)

    An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation.(CVE-2023-35788)

    A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on     corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it     has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel     panic.(CVE-2023-3212)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against     attackers with the stated 'When modifying the block device while it is mounted by the filesystem'     access.(CVE-2023-34256)

    A use after free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw     could allow a local user to cause a denial of service problem.(CVE-2023-2985)

    A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol.
    This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion     failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the     system.(CVE-2023-2156)

    An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(fepriv-gt;sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(fepriv-gt;sem) may block the process.(CVE-2023-31084)

    In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the     drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually     an error pointer).(CVE-2023-22998)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit     0323bce598eea038714f941ce2b22541c46d488f.(CVE-2023-3776)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit     04c55383fa5689357bcdd2c8036725a55ed632bc.(CVE-2023-3609)

Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a     .disconnect versus dvb_device_open race condition that leads to a use-after-free.(CVE-2022-45886)

    In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This     could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.(CVE-2023-21255)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in     the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend     upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795.(CVE-2023-3610)

    An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.(CVE-2023-3611)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. This flaw allows an attacker with local user access to cause a system crash or leak internal     kernel information.(CVE-2023-3567)

    Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace.(CVE-2023-35001)

    Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()`     failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network     namespace.(CVE-2023-31248)

    bpf: Fix incorrect verifier pruning due to missing register precision taints(CVE-2023-2163)

    A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local     privilege escalation.Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a     hrtimer.We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59     (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and0e388fce7aec40992eadee654193cad345d62663     for 5.15 stable).(CVE-2023-3389)

    A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c.Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue.We recommend upgrading past     commit1240eb93f0616b21c675416516ff3d74798fdc97.(CVE-2023-3390)

    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in     drivers/media/pci/saa7134/saa7134-core.c.(CVE-2023-35823)

    An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c.(CVE-2023-35824)
