Summary
Important: kernel security update
Details

Security Fix(es):

  • kernel: net: af_can: do not leave a dangling sk pointer in can_create() (CVE-2024-56603)

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

  • kernel: crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id (CVE-2025-68724)

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

  • 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: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold (CVE-2026-31408)

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

  • 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)
