CVE-2026-46240 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: iris: Fix use-after-free in iris_release_internal_buffers() The recent change in commit 1dabf00ee206 ("media: iris: gen1: Destroy internal buffers after FW releases") introduced a regression where session_release_buf() may free the buffer. The caller, iris_release_internal_buffers(), continued to access `buffer` after the call, leading to a potential use-after-free. Fix this by setting BUF_ATTR_PENDING_RELEASE before calling session_release_buf(), and reverting the flag if the call fails. This ensures no dereference occurs after potential freeing.
A use-after-free vulnerability has been identified in the Linux kernel's media iris component, specifically in versions prior to the patch. The issue arises in the function 'iris_release_internal_buffers()', which accesses a buffer after it has been freed by 'session_release_buf()'. This regression was introduced by a recent change that altered the buffer release process, creating a window for potential exploitation. The vulnerability could lead to memory corruption or arbitrary code execution.
Users can apply the patch available in the Linux kernel stable tree to address this vulnerability. The patched version can be downloaded from the official Linux kernel repository.
