medium Nessus Plugin ID 371117

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

* kernel: calipso: Don't call calipso functions for AF_INET sk. (CVE-2025-38147)

* kernel: ipv4: raw: reject IP_HDRINCL packets with ihl < 5 (CVE-2026-64114)

* kernel: net/smc: reject CHID-0 ACCEPT that matches an empty ism_dev slot (CVE-2026-64048)

* kernel: ALSA: hda/cs35l41: Fix firmware load work teardown (CVE-2026-64481)

* kernel: fuse: re-lock request before returning from fuse_ref_folio() (CVE-2026-64266)

* kernel: ipv4: fib: free fib_alias with kfree_rcu() on insert error path (CVE-2026-64572)

* kernel: drm/amd/display: set new_stream to NULL after release (CVE-2026-68236)

* kernel: ALSA: seq: close a re-opened queue timer in the destructor (CVE-2026-68202)

* kernel: drm/dp/mst: fix buffer overflows in sideband chunk accumulation (CVE-2026-68278)

* kernel: drm/amdgpu: fix lifetime issue of amdgpu_vm_get_task_info_pasid() (CVE-2026-68245)

* kernel: ovl: check access to copy_file_range source with src mounter creds (CVE-2026-68448)

* kernel: xfs: bounds-check buffer log item's dirty bitmap (CVE-2026-80536)

* kernel: inet: frags: strip GSO state from fragments before reassembly (CVE-2026-80590)

* kernel: drm/vmwgfx: use check_add_overflow for shader size+offset bound (CVE-2026-80887)

* kernel: perf: Fix use-after-free when perf mmap() revival races with the last munmap() (CVE-2026-89791)

* kernel: drm/amdkfd: Add TLB flush after MES queue eviction/suspension (CVE-2026-89811)

* kernel: perf: Fix addr_filter_ranges lifetime (CVE-2026-93817)

* kernel: drm/amdgpu: Bound GPIO I2C table entry count from VBIOS (CVE-2026-97493)

Bug Fix(es) and Enhancement(s):

* Backport request: bonding: only set speed/duplex to unknown, if getting speed failed [rhel-10.2.z] (JIRA:RHEL-179066)

* RTLA segfaults on freed memory access on double SIGINT [rhel-10.2.z] (JIRA:RHEL-193031)

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.

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.

Solution

Update the affected packages.
