CVE-2026-45974

A flaw was found in the Linux kernel's btrfs filesystem. The btrfsquotaenable function contains a logic error where it attempts to access an invalid memory location if a specific key is not found during a search operation. This incorrect handling of search results can lead to invalid leaf access,...

CVE-2026-45934

CVE-2026-45934 covers a Linux kernel btrfs issue where non-consecutive gaps in chunk allocation can create overlapping chunk maps, leading to aborts of filesystem operations (e.g., insert_dev_extents in btrfs_create_pending_block_groups) and a DoS-like effect. Public records describe the root cau...
