Description
This security bulletin contains information about 1 vulnerability.
1) Use-after-free (CVE-ID: CVE-2026-98776)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 5.7 [CVSS:4.0/AV:L/AC:L/AT:P/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 through kernel memory corruption.
The vulnerability exists due to use-after-free in the Linux kernel binderfs device creation path when a device entry is removed concurrently with its creation. A local user can race device creation with unlinkat() to cause binder_add_device() to write to a freed device object, potentially corrupting kernel memory and causing a denial of service.
