CVE-2026-46129

A flaw was found in the Linux kernel, specifically within the btrfs filesystem. This vulnerability, a double free, occurs in the createspaceinfo function's error handling path. When an internal object initialization fails, the system attempts to release memory twice for the same resource. This ca...

CVE-2026-46164

A flaw was found in the Linux kernel's btrfs filesystem. This vulnerability, a double free, occurs in the createspaceinfosubgroup function's error handling path. When kobjectinitandadd fails, a memory region can be freed twice. This can lead to memory corruption, potentially resulting in a denial...

CVE-2026-46159

A flaw was found in the btrfs filesystem within the Linux kernel. A Time-of-check to time-of-use TOCTOU race condition in the btrfsioctlspaceinfo function allows a local attacker to exploit a timing window. This occurs when the system counts entries for allocation size and then fills a buffer, bu...
