In the Linux kernel, the following vulnerability has been resolved: loop: Check for overflow while configuring loop The userspace can configure a loop using an ioctl call, wherein a configuration of type loop_config is passed (see lo_ioctl()'s case on line 1550 of drivers/block/loop.c). This proceeds to call loop_configure() which in turn calls loop_set_status_from_info() (see line 1050 of loop.c), passing &config->info which is of type loop_info64*. This function then sets the appropriate values, like the offset. loop_device has lo_offset of type loff_t (see line 52 of loop.c), which is typdef-chained to long long, whereas loop_info64 has lo_offset of type __u64 (see line 56 of include/uapi/linux/loop.h). The function directly copies offset from info to the device as follows (See line 980 of loop.c): lo->lo_offset = info->lo_offset; This results in an overflow, which triggers a warning in iomap_iter() due to a call to iomap_iter_done() which has: WARN_ON_ONCE(iter->iomap.offset > iter->pos); Thus, check for negative value during loop_set_status_from_info().

Tenable has extracted the preceding description block directly from the EulerOS Virtualization 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.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993283 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    loop: Check for overflow while configuring loop

    The userspace can configure a loop using an ioctl call, wherein     a configuration of type loop_config is passed (see lo_ioctl()'s     case on line 1550 of drivers/block/loop.c). This proceeds to call     loop_configure() which in turn calls loop_set_status_from_info()     (see line 1050 of loop.c), passing &config->info which is of type     loop_info64*. This function then sets the appropriate values, like     the offset.

    loop_device has lo_offset of type loff_t (see line 52 of loop.c),     which is typdef-chained to long long, whereas loop_info64 has     lo_offset of type __u64 (see line 56 of include/uapi/linux/loop.h).

    The function directly copies offset from info to the device as     follows (See line 980 of loop.c):
            lo->lo_offset = info->lo_offset;

    This results in an overflow, which triggers a warning in iomap_iter()     due to a call to iomap_iter_done() which has:
            WARN_ON_ONCE(iter->iomap.offset > iter->pos);

    Thus, check for negative value during loop_set_status_from_info().

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - loop: Check for overflow while configuring loop The userspace can configure a loop using an ioctl call,     wherein a configuration of type loop_config is passed (see lo_ioctl()'s case on line 1550 of     drivers/block/loop.c). This proceeds to call loop_configure() which in turn calls     loop_set_status_from_info() (see line 1050 of loop.c), passing &config->info which is of type     loop_info64*. This function then sets the appropriate values, like the offset. loop_device has lo_offset     of type loff_t (see line 52 of loop.c), which is typdef-chained to long long, whereas loop_info64 has     lo_offset of type __u64 (see line 56 of include/uapi/linux/loop.h). The function directly copies offset     from info to the device as follows (See line 980 of loop.c): lo->lo_offset = info->lo_offset; This results     in an overflow, which triggers a warning in iomap_iter() due to a call to iomap_iter_done() which has:
    WARN_ON_ONCE(iter->iomap.offset > iter->pos); Thus, check for negative value during     loop_set_status_from_info(). Bug report:

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

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

The version of kernel installed on the remote host is prior to 5.10.144-127.601. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-020 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    i2c: Fix a potential use after free

    Free the adap structure only after we are done using it.This patch just moves the put_device() down a bit     to avoid theuse after free.

    [wsa: added comment to the code, added Fixes tag] (CVE-2019-25162)

    In the Linux kernel, the following vulnerability has been resolved:

    tun: avoid double free in tun_free_netdev (CVE-2021-47082)

    A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

    A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service. (CVE-2022-2153)

    A use-after-free flaw was found in the Linux kernel's POSIX CPU timers functionality in the way a user     creates and then deletes the timer in the non-leader thread of the program. This flaw allows a local user     to crash or potentially escalate their privileges on the system. (CVE-2022-2585)

    It was discovered that a nft object or expression could reference a nft set on a different nft table,     leading to a use-after-free once that table was deleted. (CVE-2022-2586)

    A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the     Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege     escalation problem. (CVE-2022-2588)

    Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow     an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

    An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

    An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the     bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to     gain unauthorized access to data. (CVE-2022-2905)

    A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

    A use-after-free flaw was found in io_uring in the Linux kernel. This flaw allows a local user to trigger     the issue if a signalfd or binder fd is polled with the io_uring poll due to a lack of io_uring POLLFREE     handling. (CVE-2022-3176)

    A vulnerability was found in Linux Kernel. It has been classified as critical. This affects the function     devlink_param_set/devlink_param_get of the file net/core/devlink.c of the component IPsec. The     manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier     VDB-211929 was assigned to this vulnerability. (CVE-2022-3625)

    An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

    An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of     service can occur upon binding to an already bound chain. (CVE-2022-39190)

    A race condition in the Linux kernel's EFI capsule loader driver was found in the way it handled write and     flush operations on the device node of the EFI capsule. A local user could potentially use this flaw to     crash the system. (CVE-2022-40307)

    mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is     not held during a PUD move. (CVE-2022-41222)

    A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw     allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4744)

    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

    The upstream advisory describes this issue as follows:

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target     system in order to exploit this vulnerability.

    The specific flaw exists within the processing of seg6 attributes. The issue results from the lack of     proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
    An attacker can leverage this in conjunction with other vulnerabilties to escalate privileges and execute     arbitrary code in the context of the kernel. (CVE-2023-2860)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The version of kernel installed on the remote host is prior to 4.14.294-220.533. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1852 advisory.

    An out-of-bounds write flaw was found in the Linux kernel's framebuffer-based console driver     functionality in the way a user triggers ioctl FBIOPUT_VSCREENINFO with malicious data. This flaw allows a     local user to crash or potentially escalate their privileges on the system. (CVE-2021-33655)

    A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures.
    Internal memory locations could be returned to userspace.  A local attacker with the permissions to insert     eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit     mitigations in place for the kernel. (CVE-2021-4159)

    An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

    A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

    A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service. (CVE-2022-2153)

    A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the     Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege     escalation problem. (CVE-2022-2588)

    An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

    A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

    A flaw was found in the Linux kernel's networking code. A use-after-free was found in the way the sch_sfb     enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed)     into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of     service. (CVE-2022-3586)

    A memory access flaw was found in the Linux kernel's XEN hypervisor for the virtual machine. This flaw     allows a local user to crash the system or potentially escalate their privileges on the system.
    (CVE-2022-36123)

    An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

    A memory corruption flaw was found in the Linux kernel's Netfilter subsystem in the way a local user uses     the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash     the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.
    (CVE-2022-36946)

    An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

    A race condition in the Linux kernel's EFI capsule loader driver was found in the way it handled write and     flush operations on the device node of the EFI capsule. A local user could potentially use this flaw to     crash the system. (CVE-2022-40307)

    mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.
    (CVE-2022-42703)

    In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when     setting HMAC data.

    The upstream advisory describes this issue as follows:

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target     system in order to exploit this vulnerability.

    The specific flaw exists within the processing of seg6 attributes. The issue results from the lack of     proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
    An attacker can leverage this in conjunction with other vulnerabilties to escalate privileges and execute     arbitrary code in the context of the kernel. (CVE-2023-2860)
