In the Linux kernel, the following vulnerability has been resolved: net: fix possible store tearing in neigh_periodic_work() While looking at a related syzbot report involving neigh_periodic_work(), I found that I forgot to add an annotation when deleting an RCU protected item from a list. Readers use rcu_deference(*np), we need to use either rcu_assign_pointer() or WRITE_ONCE() on writer side to prevent store tearing. I use rcu_assign_pointer() to have lockdep support, this was the choice made in neigh_flush_dev().

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-422 advisory.

    2024-07-03: CVE-2023-52522 was added to this advisory.

    2024-07-03: CVE-2023-52559 was added to this advisory.

    2024-07-03: CVE-2023-52523 was added to this advisory.

    2024-06-06: CVE-2023-52481 was added to this advisory.

    2024-06-06: CVE-2023-52476 was added to this advisory.

    2024-06-06: CVE-2023-52477 was added to this advisory.

    2024-02-01: CVE-2024-0641 was added to this advisory.

    A flaw in the kernel Xen event handler can cause a deadlock with Xen console handling in unprivileged Xen     guests. (CVE-2023-34324)

    An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs     due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to     executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute     arbitrary code in the context of the kernel. (CVE-2023-39191)

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

    perf/x86/lbr: Filter vsyscall addresses (CVE-2023-52476)

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

    usb: hub: Guard against accesses to uninitialized BOS descriptors (CVE-2023-52477)

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

    arm64: errata: Add Cortex-A520 speculative unprivileged load workaround (CVE-2023-52481)

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

    net: fix possible store tearing in neigh_periodic_work() (CVE-2023-52522)

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

    bpf, sockmap: Reject sk_msg egress redirects to non-TCP sockets (CVE-2023-52523)

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

    iommu/vt-d: Avoid memory allocation in iommu_suspend() (CVE-2023-52559)

    A denial of service vulnerability was found in tipc_crypto_key_revoke in net/tipc/crypto.c in the Linux     kernel's TIPC subsystem. This flaw allows guests with local user privileges to trigger a deadlock and     potentially crash the system. (CVE-2024-0641)

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 5.15.136-90.144. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-029 advisory.

    A denial of service vulnerability was found in tipc_crypto_key_revoke in net/tipc/crypto.c in the Linux     kernel's TIPC subsystem. This flaw allows guests with local user privileges to trigger a deadlock and     potentially crash the system. (CVE-2024-0641)

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 5.10.198-187.748. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-042 advisory.

    An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error     in do_div(sz,mtd->erasesize), used indirectly by ctrl_cdev_ioctl, when mtd->erasesize is 0.
    (CVE-2023-31085)

    A flaw in the kernel Xen event handler can cause a deadlock with Xen console handling in unprivileged Xen     guests. (CVE-2023-34324)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage     collection, it is possible to underflow the reference counter causing a use-after-free vulnerability.

    We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8. (CVE-2023-4244)

    A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was     assumed to be associated with a device before calling __ip_options_compile, which is not always the case     if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash     the system. (CVE-2023-42754)

    A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD     and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`.
    This issue may allow a local user to crash the system. (CVE-2023-42756)

    Rejected reason: CVE-2023-4881 was wrongly assigned to a bug that was deemed to be a non-security issue by     the Linux kernel security team. (CVE-2023-4881)

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

    netfilter: nft_set_rbtree: skip sync GC for new elements in this transaction

    New elements in this transaction might expired before such transactionends. Skip sync GC for such elements     otherwise commit path might walkover an already released object. Once transaction is finished, async     GCwill collect such expired element. (CVE-2023-52433)

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

    ring-buffer: Do not attempt to read past commit (CVE-2023-52501)

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

    net: fix possible store tearing in neigh_periodic_work() (CVE-2023-52522)

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

    serial: 8250_port: Check IRQ data before use (CVE-2023-52567)

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

    net: rds: Fix possible NULL-pointer dereference (CVE-2023-52573)

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

    team: fix null-ptr-deref when team device type is changed (CVE-2023-52574)

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

    net: bridge: use DEV_STATS_INC() (CVE-2023-52578)

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

    netfilter: nftables: exthdr: fix 4-byte stack OOB write

    If priv->len is a multiple of 4, then dst[len / 4] can write pastthe destination array which leads to     stack corruption.

    This construct is necessary to clean the remainder of the registerin case ->len is NOT a multiple of the     register size, so make itconditional just like nft_payload.c does.

    The bug was added in 4.1 cycle and then copied/inherited whentcp/sctp and ip option support was added.

    Bug reported by Zero Day Initiative project (ZDI-CAN-21950,ZDI-CAN-21951, ZDI-CAN-21961). (CVE-2023-52628)
