CVE-2026-52936

A flaw was found in the Linux kernel's jitterentropy cryptographic module. A long-held spinlock during entropy collection could cause parallel readers to stall. This issue allows a local attacker to trigger a Denial of Service DoS by causing contention for the shared lock, making the system...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/mad: Improved handling of time-out WRs for mad agents. The current timeout handler for mad agents acquires/releases the madagentpriv lock for every time-out WR. This causes heavy locking contention when multiple WRs need to ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: can: isotp: isotpsendmsg: added a result check for waiteventinterruptible. The waiteventinterruptible function is used to wait for complete transmission, but the result of this function, which may be interrupted, is not checked...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/msm/mdp5: Fixed the issue where global state locks were locked backoff. We need to acquire the lock after the early return in the !hwpipe case. Otherwise, we might encounter contention but still return 0. This fix addresses a...

CVE-2026-10634 Use-after-free in Zephyr native TCP net_tcp_foreach() due to dropping tcp_lock during the callback

Zephyr's native TCP stack iterates the global connection list in nettcpforeach subsys/net/ip/tcp.c using the SYSSLISTFOREACHCONTAINERSAFE macro, which caches a pointer to the next list node. Prior to this fix the function released tcplock while invoking the per-connection callback and re-acquired...
