Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrumacltcam: A memory leak has been fixed when canceling the rehash operation. The rehash operation is rescheduled with a delay if the number of credits at the end of the operation is not negative—this indicates that t...

Astra Linux – Vulnerability in Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrumacltcam: A memory leak was fixed during the rehash operation. The rehash operation delays the migration of filters from one region to another. This is achieved by iterating over all chunks all filters with the same...

CVE-2026-74727

In the Linux kernel, the following vulnerability has been resolved: ovpn: skip rehash for peers already removed from byid ovpnnlpeersetdoit resolves the target peer via ovpnpeergetbyid before taking ovpn-lock. In the window between the lookup which only takes a refcount and the subsequent...

CVE-2026-74727

A race condition in the Linux kernel's ovpn module (in-kernel OpenVPN) causes a Use-After-Free . When a peer is removed concurrently (via OVPN_CMD_PEER_DEL, keepalive expiry, or socket teardown) while ovpn_nl_peer_set_doit() or the float path (ovpn_peer_endpoints_update()) holds only a refcount, ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: UDP: The auto-bound connected sockets’ hash values are unhashed when they are disconnected from the network. Suppose we bind an UDP socket to a wildcard address with a non-zero port, then connect it to a specific address, and lat...

Astra Linux – Vulnerability in OpenSSL

In addition to the crehash shell command injection identified in CVE-2022-1292, further instances where the crehash script fails to properly sanitize shell metacharacters to prevent command injection were discovered during code reviews. When CVE-2022-1292 was fixed, it wasn’t recognized that ther...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrumacltcam: Fixed a warning during rehash As previously explained, the rehash process delays the migration of filters from one region to another. This is done by iterating over all chunks all filters with the same...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net/mlx5: HWS, fixed the issue where complex rule rehash operations failed. Moving rules from one matcher to another should not fail. However, if it does fail due to various reasons, the error handling mechanism should allow t...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrumacltcam: Fixed a possible use-after-free during rehash. The rehash process delays the migration of filters from one region to another based on the number of available credits. If the number of credits is...
