Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: sched/deadline: Only the freecpus field is set for online runqueues. Commit 16b269436b72 “sched/deadline: Modified cpudl::freecpus to reflect rd-online“” introduced the cpudlset/clearfreecpu functions, allowing the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: pagepool: Always add GFPNOWARN for ATOMIC allocations. Driver developers often forget to include GFPNOWARN when allocating pages from the data path. This is annoying for users, as OOM Out-of-Memory conditions are common. We can...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: drm/atmel-hlcdc: fixed a memory leak from the atomicDestroystate callback. After several commits, the amount of slated memory increased. Some drmcrtccommit objects were not freed. The atomicDestroystate callback only freed the...

GHSA-239G-2685-54X3 install: TOCTOU symlink race (unlink-then-create without O_EXCL) allows arbitrary file overwrite

copyfile in install/src/install.rs removes the destination then recreates it by pathname via File::create / fs::copy without OEXCL/createnew. Between the unlink and the recreate, a local attacker with write access to the destination directory can drop in a symlink and redirect the write. Impact:...

CVE-2026-10653

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...

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...
