CVE-2026-23423

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel related to memory management within the btrfs uring read extent() function. Specifically, the pages object may not be freed under certain error conditions, potentially leading to memory leaks. This occurs when allocations fail or when btrfs encoded read regular fill pages() does not return -EIOCBQUEUED, causing the cleanup section to execute without proper deferred execution handling.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
