Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: BPF: Fixed a memory leak in the LRU and LRUPERCPU hash maps The LRU and LRUPERCPU maps allocate a new element during updates, before locking the target hash table bucket. Immediately afterwards, the maps attempt to lock the bucke...

CVE-2026-97542

A flaw was found in the Linux kernel's XFS file system. When performing online repair of an allocation group free list AGFL, the kernel fails to check return values during bitmap processing, silently ignoring errors. A local user capable of triggering file system repair operations could cause the...

CVE-2026-14367

CVE-2026-14367 affects the Zephyr RTOS I3C IBI subsystem in drivers/i3c/i3c_ibi_workq.c. A statically-allocated work-node free-list (sys_slist_t) is accessed without synchronization: ISR-context callers invoke sys_slist_get() while the workqueue thread calls sys_slist_append(). This data race can...

CVE-2026-10653

The CVE-2026-10653 issue affects the Zephyr net_buf library (lib/net_buf/buf.c). It relies on non-atomic operations for two reference counters: the per-header buf->ref and the per-data-block ref_count. Under true concurrency, two independent unrefs can observe the same prior value and both tre...

CVE-2026-10653 Non-atomic `net_buf` reference counts cause double-free / free-list corruption under concurrent unref

The Zephyr netbuf library lib/netbuf/buf.c manipulated both of its reference counts -- the per-header buf-ref and the per-data-block refcount at the start of each variable/heap data allocation -- with plain non-atomic C operators buf-ref++, if --buf-ref 0, if --refcount. The API is documented as...
