Summary
Important: kernel security update
Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: net/sched: Make cake_enqueue return NET_XMIT_CN when past buffer_limit (CVE-2025-39766)

  • kernel: scsi: qla2xxx: Fix improper freeing of purex item (CVE-2025-68741)

  • kernel: libceph: make decode_pool() more resilient against corrupted osdmaps (CVE-2025-71116)

  • kernel: libceph: prevent potential out-of-bounds reads in handle_auth_done() (CVE-2026-22984)

  • kernel: libceph: replace overzealous BUG_ON in osdmap_apply_incremental() (CVE-2026-22990)

  • kernel: Linux kernel: Denial of Service in libceph OSD client due to unreset sparse-read state (CVE-2026-23136)

  • kernel: net/sched: cls_u32: use skb_header_pointer_careful() (CVE-2026-23204)

  • kernel: Linux kernel: Use-after-free in traffic control (act_ct) may lead to denial of service or privilege escalation (CVE-2026-23270)

  • kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling (CVE-2026-23401)

  • kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache (CVE-2026-31402)

  • kernel: can: raw: fix ro->uniq use-after-free in raw_rcv() (CVE-2026-31532)

  • kernel: usbip: validate number_of_packets in usbip_pack_ret_submit() (CVE-2026-31607)

  • kernel: md/bitmap: fix GPF in write_page caused by resize race (CVE-2026-43163)

  • kernel: RDMA/umem: Fix double dma_buf_unpin in failure path (CVE-2026-43128)

  • kernel: "Dirty Frag" is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel (CVE-2026-43284)

  • kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel (CVE-2026-46300)

  • kernel: Read root-owned files as an unprivileged user (CVE-2026-46333)
