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-2026-53031 bpf: Validate node_id in arena_alloc_pages()

In the Linux kernel, the following vulnerability has been resolved: bpf: Validate nodeid in arenaallocpages arenaallocpages accepts a plain int nodeid and forwards it through the entire allocation chain without any bounds checking. Validate nodeid before passing it down the allocation chain in...

CVE-2026-53031

The CVE-2026-53031 issue affects the Linux kernel BPF unit: arena_alloc_pages() accepts a plain int node_id and forwards it through the allocation chain without bounds checks. A fix validates node_id before passing it down, mitigating potential memory corruption that could lead to DoS or instabil...

CVE-2026-52976

The CVE-2026-52976 issue affects the Linux kernel drm/xe driver. Two error-handling paths in xe_exec_queue_create_ioctl() can lead to memory corruption: (1) on xe_hw_engine_group_add_exec_queue() failure, the cleanup jumps to cleanup without xe_exec_queue_kill(), potentially leaving a queue in th...

CVE-2026-52973

Summary: CVE-2026-52973 relates to the Linux kernel futex subsystem. The issue arises from dropping the CLONE_THREAD requirement for private default futex hash allocation, because the function need_futex_hash_allocate_default() relied on strict pthread semantics. This misinteraction with CLONE_TH...
