CVE-2026-63946

CVE-2026-63946: In the Linux kernel Bluetooth ISO path, iso_recv_frame can use a freed sk due to holding iso_conn_lock but releasing it before using conn->sk. The fix replaces a bare pointer read with iso_sock_hold(conn), which holds the sock while the spinlock is still held and atomically inc...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix race condition in mptcpschedulework syzbot reported use-after-free in mptcpschedulework 1 Issue here is that mptcpschedulework schedules a work, then gets a refcount on sk-skrefcnt if the work was scheduled. This...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: In the net: rose module, the function rosekillbydevice collects sockets into a local array, and then iterates over those arrays to disconnect sockets bound to devices that are being shut down. The loop mistakenly indexes arraycnt...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Avoid per-cpu hold underflow in aagetbuffer. When aagetbuffer retrieves data from the per-cpu list, it conditionally decreases cache-hold. If hold reaches 0 while count remains non-zero, the unsigned decrement wraps to...

CVE-2026-52912

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfqueue: hold bridge skb-dev while queued brpassframeup rewrites skb-dev from the ingress port to the bridge master before queueing bridge LOCALIN packets. NFQUEUE only holds references on state.in/out and bridge...

CVE-2026-52912

The CVE-2026-52912 affects the Linux kernel netfilter nf_queue handling of bridge LOCAL_IN traffic. br_pass_frame_up() rewrites skb->dev from the ingress port to the bridge master before queueing, allowing a queued bridge packet to retain a freed bridge master in skb->dev. On reinjection, b...
