Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Net: Consume xmit errors of GSO frames. udpgrofrglist.sh and udpgrobench.sh are the most flaky tests currently in NIPA. They fail in exactly the same way. The TCP GRO test occasionally stalls, and the test terminates after 10...

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

A flaw was discovered in the Linux kernel’s Traffic Control TC subsystem. Using a specific networking configuration—redirecting egress packets to ingress using the TC “mirred” action—a local unprivileged user could trigger a CPU soft lockup ABBA deadlock when the transport protocol in use TCP or...

PT-2024-35613

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.12.0-rc4-dirty Description A use-after-free issue has been identified in the Linux kernel's sunrpc module, specifically related to the kernel's TCP socket handling. This issue arises when the TCP socket in a...

kernel: mptcp: ensure snd_una is properly initialized on connect

A vulnerability was found in the Linux kernel's match component in the initialization of the snduna variable while establishing a connection. The issue arises when retransmission occurs after a fallback, leaving the snduna sequence number uninitialized, leading to unpredictable behavior and...

kernel: tcp: avoid too many retransmit packets

A vulnerability was found in the tcpretransmittimer function in the Linux kernel's TCP implementation. This issue occurs when a TCP socket uses TCPUSERTIMEOUT and the peer's window retracts to zero, leading to excessive retransmission of packets every two milliseconds for up to four minutes after...

CVE-2021-47131 net/tls: Fix use-after-free after the TLS device goes down and up

In the Linux kernel, the following vulnerability has been resolved: net/tls: Fix use-after-free after the TLS device goes down and up When a netdev with active TLS offload goes down, tlsdevicedown is called to stop the offload and tear down the TLS context. However, the socket stays alive, and it...
