Description
This security bulletin contains information about 1 vulnerability.
1) Use-after-free (CVE-ID: CVE-2026-64468)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to use-after-free in binder_free_transaction() when freeing binder transactions. A local user can trigger a race condition involving a binder transaction to cause a denial of service.
The issue occurs because the target process can be freed after its reference is read and before its inner lock is acquired.
Remediation
Install update from vendor's website.
