CVE-2026-74321

CVE-2026-74321 relates to the Linux kernel’s btrfs subsystem. The issue was an invalid pointer dereference in __btrfs_run_delayed_refs() during the early loop when btrfs_select_ref_head() could return an ERR_PTR(-EAGAIN). If that happened, the code could enter a state where locked_ref was not NUL...
