media: iris: Fix use-after-free in iris_release_internal_buffers()_CVE-2026-46240

    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: iris: Fix use-after-free in iris_release_internal_buffers()\n\nThe recent change in commit 1dabf00ee206 (\"media: iris: gen1: Destroy\ninternal buffers after FW releases\") introduced a regression where\nsession_release_buf() may free the buffer. The caller,\niris_release_internal_buffers(), continued to access `buffer` after the\ncall, leading to a potential use-after-free.\n\nFix this by setting BUF_ATTR_PENDING_RELEASE before calling\nsession_release_buf(), and reverting the flag if the call fails. This\nensures no dereference occurs after potential freeing.",
