CVE-2024-56759

CVE-2024-56759 concerns the Linux kernel: when Btrfs COWs a tree block with tracing enabled (trace_btrfs_cow_block) and preemption is on, a use-after-free can occur on the COWed extent buffer. The root cause is that tracepoint handling could observe a buffer after it is freed via RCUs, if preempt...

CVE-2024-56758

CVE-2024-56758 affects the Linux kernel (btrfs) and describes a race where, after folio unlock during relocation, another thread can modify the folio mapping before folio_lock() and lead to an invalid page, potentially causing a NULL pointer dereference during concurrent transaction aborts. The i...

CVE-2024-56581

CVE-2024-56581 affects the Linux kernel’s Btrfs code. The issue is a use-after-free in btrfs_ref_tree_mod() after inserting a new ref entry into a block entry’s rb-tree when an unexpected action (BTRFS_DROP_DELAYED_REF) is encountered. The error path freed the ref entry without removing it from t...
