Important: kernel security update
The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: TIPC message reassembly use-after-free remote code execution vulnerability (CVE-2024-36886) * kernel: ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() (CVE-2021-47548) * kernel: net: hns3: fix use-after-free bug in hclgevf_send_mbx_msg (CVE-2021-47596) * kernel: vt: fix memory overlapping when deleting chars in the buffer (CVE-2022-48627) * kernel: can: j1939: prevent deadlock by changing j1939_socks_lock to rwlock (CVE-2023-52638) * kernel: mm/vmscan: fix a bug calling wakeup_kswapd() with a wrong zone index (CVE-2024-26783) * kernel: net/mlx5e: Use a memory barrier to enforce PTP WQ xmit submission tracking occurs after populating the metadata_map (CVE-2024-26858) * kernel: netfilter: nf_tables: use timestamp to check for set element timeout (CVE-2024-27397) * kernel: nvme: fix reconnection fail due to reserved tag allocation (CVE-2024-27435) * kernel: net: ena: Fix incorrect descriptor free behavior (CVE-2024-35958) * kernel: tcp: Use refcount_inc_not_zero() in tcp_twsk_unique(). (CVE-2024-36904) * kernel: lib/test_hmm.c: handle src_pfns and dst_pfns allocation failure (CVE-2024-38543) * kernel: r8169: Fix possible ring buffer corruption on fragmented Tx packets. (CVE-2024-38586) * kernel: net: micrel: Fix receiving the timestamp in the frame for lan8841 (CVE-2024-38593) * kernel: netfilter: tproxy: bail out if IP has been disabled on the device (CVE-2024-36270) * kernel: octeontx2-af: avoid off-by-one read from userspace (CVE-2024-36957) * kernel: blk-cgroup: fix list corruption from resetting io stat (CVE-2024-38663) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
