Threats Tagged 'cve-2026-80714'

Multiple security vulnerabilities affecting the Linux kernel have been addressed in a security update. These include fixes for use-after-free, out-of-bounds reads, integer overflows, memory corruption, denial of service, and buffer overflow issues across various kernel subsystems such as fbcon, smb, drm/amdgpu, netfilter, accel/ivpu, and others. The update is applicable to SUSE and Red Hat Enterprise Linux distributions. The vendor has released official patches to remediate these vulnerabilities.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: fbcon: Set fb_display[i]->mode to NULL when the mode is released (CVE-2025-40323) * kernel: ext4: fix e4b bitmap inconsistency reports (CVE-2026-45942) * kernel: drm/amdgpu/vcn3: Prevent OOB reads when parsing dec msg (CVE-2026-46230) * kernel: drm/amdgpu/vcn4: Prevent OOB reads when parsing IB (CVE-2026-46204) * kernel: drm/amdgpu/vcn4: Prevent OOB reads when parsing dec msg (CVE-2026-46199) * kernel: arm64: tlb: Flush walk cache when unsharing PMD tables (CVE-2026-63875) * kernel: net: mana: Fix TOCTOU double-fetch of hwc_msg_id from DMA buffer (CVE-2026-64034) * kernel: perf/core: Detach event groups during remove_on_exec (CVE-2026-64556) * kernel: Linux kernel: libceph stack out-of-bounds write via crafted OSDMap (CVE-2026-68159) * kernel: libceph: refresh auth->authorizer_buf{,_len} after authorizer update (CVE-2026-68156) * kernel: Linux kernel (libceph): Denial of Service due to malformed monitor maps (CVE-2026-68155) * kernel: drm/amdgpu: Fix context pstate override handling (CVE-2026-68273) * kernel: perf: Reject exited events as group leaders (CVE-2026-74753) 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.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: drm/amdgpu: Fix fence put before wait in amdgpu_amdkfd_submit_ib (CVE-2026-31566) * kernel: netfilter: nf_queue: hold bridge skb->dev while queued (CVE-2026-52912) * kernel: Linux kernel: PPPoE memory corruption via stale pointer (CVE-2026-68121) * kernel: Linux kernel IPVS: Denial of Service due to stale memory references (CVE-2026-80714) * kernel: nvme-tcp: reject a read that transferred too few bytes (CVE-2026-89480) 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.

In the Linux kernel, the following vulnerability has been resolved: ipvs: do not propagate one-packet flag to synced conns Synced connections can be created before their destination exists. When the destination is later added, ip_vs_bind_dest() copies connection flags from the destination into cp->flags. IP_VS_CONN_F_ONE_PACKET connections are not synced. If a synced connection inherits IP_VS_CONN_F_ONE_PACKET while it is already hashed, expiry can treat it as a one-packet connection and skip unlinking the existing conn_tab node, leaving stale hash nodes pointing at a freed struct ip_vs_conn. Drop IP_VS_CONN_F_ONE_PACKET from destination flags when binding synced connections.
