In the Linux kernel, the following vulnerability has been resolved: bpf: Don't redirect packets with invalid pkt_len Syzbot found an issue [1]: fq_codel_drop() try to drop a flow whitout any skbs, that is, the flow->head is null. The root cause, as the [2] says, is because that bpf_prog_test_run_skb() run a bpf prog which redirects empty skbs. So we should determine whether the length of the packet modified by bpf prog or others like bpf_prog_test is valid before forwarding it directly.

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

  - bpf: Don't redirect packets with invalid pkt_len Syzbot found an issue [1]: fq_codel_drop() try to drop a     flow whitout any skbs, that is, the flow->head is null. The root cause, as the [2] says, is because that     bpf_prog_test_run_skb() run a bpf prog which redirects empty skbs. So we should determine whether the     length of the packet modified by bpf prog or others like bpf_prog_test is valid before forwarding it     directly. (CVE-2022-49975)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel installed on the remote host is prior to 5.4.214-120.368. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-036 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)

    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)

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

    thermal: Fix NULL pointer dereferences in of_thermal_ functions (CVE-2021-47202)

    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)

    In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input     validation. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-223375145References: Upstream kernel (CVE-2022-20369)

    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)

    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)

    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)

    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)

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

    nvme-tcp: fix UAF when detecting digest errors (CVE-2022-48686)

    In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when     setting HMAC data. The SRv6 layer allows defining HMAC data that can later be used to sign IPv6 Segment     Routing Headers. This configuration is realised via netlink through four attributes: SEG6_ATTR_HMACKEYID,     SEG6_ATTR_SECRET, SEG6_ATTR_SECRETLEN and SEG6_ATTR_ALGID. (CVE-2022-48687)

    KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0 (CVE-2022-50228)

    In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the     transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- 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)

    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)
