Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: CVE-2026-99043)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 5.6 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local privileged user to cause a denial of service through a potential kernel crash.

The vulnerability exists due to use-after-free in the Linux kernel ice driver's ice_eswitch_release_repr() function when a representor is torn down while queued packets still reference its metadata_dst object. A local privileged user can trigger this teardown condition to cause a potential kernel crash when the outstanding references are subsequently used.
