CVE-2026-53277

A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on arm64 architectures. This vulnerability occurs because certain page table walk operations, used in fault injection and Address Translation AT emulation, do not properly acquire a Sleepable Read-Copy Update...

CVE-2026-53252

The CVE-2026-53252 affects the Linux kernel Bluetooth HCI path. Root cause: memory leak of SRCU percpu memory when device init fails before hci_register_dev(), due to not cleaning up the SRCU struct on the unregistered fallback path. Fix: call cleanup_srcu_struct() in bt_host_release() fallback b...

CVE-2026-46106

CVE-2026-46106 concerns the Linux kernel eventfs remount race. The root cause is a race where eventfs_inodes are traversed while remounts are performed, due to mixing rcu_read_lock usage with SRCU and not holding eventfs_mutex during the critical walk. The fix (commit 340f0c7067a9) updates the ev...
