Description

This security bulletin contains information about 1 vulnerability.


1) Missing Release of Resource after Effective Lifetime (CVE-ID: CVE-2026-98777)

CWE-ID: CWE-772 - Missing Release of Resource after Effective Lifetime

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 through exhaustion of system-wide file resources.

The vulnerability exists due to missing resource release in the Linux kernel Binder transaction cleanup when a TF_UPDATE_TXN transaction supersedes a pending asynchronous transaction in a frozen process. A local user can repeatedly trigger transaction replacement to leak binder_txn_fd_fixup entries and their file references, eventually exhausting the system-wide file limit.

The leaked resources survive process exit.
