AI-suggested
A patch is available and should be applied to affected linux-hwe-edge kernel versions. The vendor advisory confirms the issue is fixed. Users should update to the patched kernel versions to remediate this vulnerability.
Description
A potential memory leak vulnerability in the Linux kernel's broadsheetfb framebuffer driver was fixed. The issue involved memory allocated for pagerefs in fb_deferred_io_init() not being freed on error paths, which could lead to resource exhaustion. The fix involves calling fb_deferred_io_cleanup() to properly free memory. This vulnerability affects specific versions of the linux-hwe-edge kernel and has been patched.
