Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/tls: tlsswspliceread fails after an async decrypt failure. When an async decrypt fails, tlsdecryptdone records the error in ctx-asyncwait.err and calls tlserrabort, which stores the error in skerr. Both tlsswrecvmsg and...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: net/tls: fix kernel panic when allocpage failed We cannot set fraglist to NULL pointer when allocpage failed. It will be used in tlsstrpcheckqueueok when the next time tlsstrpreadsock is called. This is because we don’t reset...

kernel: tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock()

A flaw was found in the Linux kernel’s TLS implementation net/tls/tlsdevice.c. The function getnetdevforsock is invoked during setsockopt, which is not executed under RCU Read-Copy-Update protection. It previously used skdstgetsk-dev, which can lead to a use-after-free UAF if the sk’s destination...

ROS-20261007-73-0073

The vulnerability of the tlsdoencryption function in the net/tls/tlssw.c component of the Linux kernel is related to the use of memory after it is freed. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

ROS-20261006-73-0059

The vulnerability of the net/tls/tlssw.c component in the Linux operating system is related to improper memory release before deleting the last reference. Exploiting this vulnerability can allow an attacker to cause a service failure remotely...

CVE-2026-80904

CVE-2026-80904 is a Linux kernel vulnerability in the net/tls (TLS offload) subsystem. When an asynchronous TLS decryption fails, tls_sw_recvmsg() and tls_sw_read_sock() correctly check async_wait.err and abort the read, but tls_sw_splice_read() performs no such check. As a result, a splice opera...
