1) Use of uninitialized resource (CVE-ID: CVE-2026-92476)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: 0 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to trigger use of an uninitialized completion.

The vulnerability exists due to use of an uninitialized resource in the Keem Bay OCS AES driver's kmb_ocs_aes_probe() routine when a device interrupt occurs after IRQ registration and before completion initialization. A local user can trigger a device interrupt during this initialization window to trigger use of an uninitialized completion.
