CVE-2026-74571

A flaw was found in the Linux kernel's btrfs filesystem. When mounting a btrfs filesystem with the rescue=ibadroots option after corrupting the block group tree root or raid stripe tree root, the system attempts to update the global block reserve. This process dereferences a missing root pointer,...

CVE-2026-72084

A flaw was found in the Linux kernel's SCSI target subsystem. An attacker, by submitting a specially crafted iSCSI TransportID during a PERSISTENT RESERVE OUT operation, could cause an out-of-bounds read. This vulnerability, which occurs due to unbounded parsing of the TransportID, can lead to a...

CVE-2026-74571

CVE-2026-74571 affects the Linux kernel/btrfs. The issue occurs when mounting with rescue=ibadroots on a corrupted block group tree, leading to a NULL pointer dereference in btrfs_update_global_block_rsv. The root cause is that btrfs_read_roots() may leave a root pointer NULL while its on-disk fe...
