CVE-2026-31480
A flaw was found in the Linux kernel. A local attacker or a user with specific privileges could exploit a race condition during CPU hotplug operations, specifically when using the 'osnoise' tracing feature. This vulnerability can lead to a system deadlock, rendering the system unresponsive and...

CVE-2026-31499
CVE-2026-31499 affects the Linux kernel Bluetooth L2CAP code. The vulnerability stems from l2cap_conn_del() canceling delayed work (info_timer and id_addr_timer) while holding conn->lock, while the corresponding work functions (l2cap_info_timeout() and l2cap_conn_update_id_addr()) also acquire...
CVE-2026-31486
The CVE-2026-31486 entry concerns the Linux kernel hwmon/pmbus/core regulator operations (get_voltage, set_voltage, list_voltage) not being mutex-protected, risking race conditions when accessing PMBus registers and shared data. The fix reworks pmbus_regulator_notify() to perform notifications vi...
CVE-2026-31480 tracing: Fix potential deadlock in cpu hotplug with osnoise

CVE-2026-31480
CVE-2026-31480 concerns a Linux kernel deadlock in CPU hotplug when tracing with osnoise. The vulnerability arises from a lock-ordering issue: a mutex_lock on interface_lock is taken while osnoise_sleep() and subsequent actions hold cpu hotplug state, followed by cpus_read_lock(), which can cause...

CVE-2026-31467
CVE-2026-31467 concerns the Linux kernel vulnerability where the bio completion path in certain process contexts (e.g., dm-verity) could call into decompression and then into vm_map_ram() with GFP_KERNEL, risking memory pressure and a potential deadlock in submit_bio_wait. The issue is tied to th...
