CVE-2026-53101
CVE-2026-53101 is a Linux kernel issue affecting the wifi mt76/mt7921 path. The root cause is a potential mutex deadlock between mt7921_roc_abort_sync and roc_work: roc_work() holds dev->mt76.mutex while cancel_work_sync() waits for roc_work() to finish. If the caller already owns the mutex, b...
CVE-2026-53100
CVE-2026-53100 affects the Linux kernel mt76 wireless driver. The deadlock occurs when remain-on-channel logic calls mt76_set_channel() while dev->mutex is already held by remain_on_channel/roc_complete, since mt76_set_channel() also locks the mutex. The fix replaces mt76_set_channel() with __...
EUVD-2026-38968
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix deadlock in remain-on-channel mt76remainonchannel and mt76roccomplete call mt76setchannel while already holding dev-mutex. Since mt76setchannel also acquires dev-mutex, this results in a deadlock. Use mt76setchann...
CVE-2026-53085
The CVE-2026-53085 issue affects the Linux kernel BPF subsystem where the open-coded task_vma iterator reads task->mm locklessly and uses mmap_read_trylock() without taking an mm reference, risking use-after-free if the task exits concurrently. The patch reads task->mm with a trylock on all...
CVE-2026-53085 bpf: fix mm lifecycle in open-coded task_vma iterator
In the Linux kernel, the following vulnerability has been resolved: bpf: fix mm lifecycle in open-coded taskvma iterator The open-coded taskvma iterator reads task-mm locklessly and acquires mmapreadtrylock but never calls mmget. If the task exits concurrently, the mmstruct can be freed as it is...
CVE-2026-53037
CVE-2026-53037 affects the Linux kernel with a deadlock in HID reset handling when a USB HID device is paired with a storage/UAS component. The issue arises because hid_pre_reset() and hid_post_reset() may perform memory allocations that touch IO, risking deadlock, so the patch switches allocatio...
CVE-2026-53037 HID: usbhid: fix deadlock in hid_post_reset()
In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix deadlock in hidpostreset You can build a USB device that includes a HID component and a storage or UAS component. The components can be reset only together. That means that hidprereset and hidpostreset are in the...
