CVE-2026-53101 wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix potential deadlock in mt7921rocabortsync rocabortsync can deadlock with rocwork. rocwork holds dev-mt76.mutex, while cancelworksync waits for rocwork to finish. If the caller already owns the same mutex,...

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 __...

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-2026-53085

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-2026-53037

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...
