Description

This security bulletin contains information about 1 vulnerability.


1) Improper resource shutdown or release (CVE-ID: CVE-2026-98778)

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to close unrelated file descriptors in a target process, potentially causing a denial of service.

The vulnerability exists due to improper resource release in the Linux kernel Binder driver when cleaning up a pending asynchronous transaction superseded by a TF_UPDATE_TXN transaction. A local user can trigger transaction replacement to cause the BINDER_TYPE_FDA cleanup handler to interpret stale buffer contents as installed file descriptor numbers and close unrelated file descriptors in the target process.
