CVE-2026-31446

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability, a use-after-free, occurs due to a timing issue when the updatesuperwork function attempts to access memory that has already been released during a filesystem unmount operation. A local attacker could potentially exploit...

CVE-2026-31448

A flaw was found in the Linux kernel's ext4 filesystem. When creating a directory or node, if an extent insertion fails, the system may not properly clear residual data. This can lead to a situation where both directory and extended attribute xattr blocks simultaneously use the same memory buffer...
