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-2026-74318

A flaw was found in the Linux kernel's btrfs filesystem. A local user could trigger a deadlock when cloning an inline extent with the flushoncommit mount option, specifically when the destination offset is greater than zero. This issue occurs due to a missing isize update during the copy operatio...

CVE-2026-74321

A flaw was found in the btrfs file system component of the Linux kernel. This vulnerability occurs in the btrfsrundelayedrefs function when an error condition is not properly handled, leading to an invalid pointer dereference. A local attacker could potentially exploit this flaw to cause a system...

CVE-2026-74319
