CVE-2026-45912

A flaw was found in the Linux kernel's ext4 filesystem. During certain file operations, specifically when splitting data extents, an issue with caching can lead to incorrect tracking of disk space. This can result in errors in space accounting, potentially impacting data integrity and the overall...

CVE-2026-45948

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs in the ext4extshiftextents function, where a memory leak can happen if the function returns prematurely without releasing a previously obtained path. A local attacker could potentially exploit this to cause a denial...
