Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: - net: tls: Fixed a use-after-free issue related to partial reads and async decryption. tlsdecryptsg does not take a reference to the pages from clearskb. Therefore, the putpage function in tlsdecryptdone releases these pages,...

Linux Kernel IPv6 VTI Subsystem Use-After-Free Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of...

CVE-2026-63801

A flaw was found in the Linux kernel. A remote attacker could exploit a use-after-free vulnerability in the Transparent Inter-Process Communication TIPC cryptographic decryption process. This flaw occurs when a network namespace, a mechanism for isolating network resources, is deallocated before ...

EUVD-2026-45467

In the Linux kernel, the following vulnerability has been resolved: tipc: fix slab-use-after-free Read in tipcaeaddecryptdone tipcaeaddecrypt goes straight from tipcbearerholdb to cryptoaeaddecryptreq without taking a reference on the netns, unlike the encrypt path. When cryptoaeaddecrypt is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: crypto: krb5enc – Fix for skipping hash verification during asynchronous decryption. The krb5encdispatchdecrypt function sets req-base.complete as the skcipher callback. This means that the caller’s own completion handler is...

CVE-2026-31719

A flaw was found in the krb5enc module of the Linux kernel's crypto subsystem. When performing asynchronous decryption, the krb5encdispatchdecrypt function incorrectly bypasses the integrity verification hash check. This issue occurs because the skcipher completion handler signals completion...

EUVD-2026-26528

In the Linux kernel, the following vulnerability has been resolved: crypto: krb5enc - fix async decrypt skipping hash verification krb5encdispatchdecrypt sets req-base.complete as the skcipher callback, which is the caller's own completion handler. When the skcipher completes asynchronously, this...

kernel: tls: wait for pending async decryptions if tls_strp_msg_hold fails

A vulnerability was found in tlsdecryptsg in net/tls/tlssw.c in networking subsystem in the Linux Kernel.In this flaw, If it fails to clone of the input skb to hold the reference to the memory it uses may lead a use-after-free...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from not waiting for asynchronous decryption to complete after a tlsstrpmsghold failure, which could lead to a UA...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: tls: Separating the handling of no-async decryption requests from async. If we are not using async, the handling is much simpler. There is no reference counting; we simply need to wait for the completion to wake us up and return...

SUSE CVE-2024-58240

In the Linux kernel, the following vulnerability has been resolved: tls: separate no-async decryption request handling from async If we're not doing async, the handling is much simpler. There's no reference counting, we just need to wait for the completion to wake us up and return its result. We...

DEBIAN-CVE-2024-50047

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix UAF in async decryption Doing an async decryption large read crashes with a slab-use-after-free way down in the crypto API. Reproducer: mount.cifs -o ...,seal,esize=1 //srv/share /mnt dd if=/mnt/largefile...

Linux Kernel Resource Management Vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a crash due to post-release reuse when the smb client performs asynchronous decryption...

SUSE CVE-2024-26800

In the Linux kernel, the following vulnerability has been resolved: tls: fix use-after-free on failed backlog decryption When the decrypt request goes to the backlog and cryptoaeaddecrypt returns -EBUSY, tlsdodecryption will wait until all async decryptions have completed. If one of them fails,...

CVE-2024-26582

In the Linux kernel, the following vulnerability has been resolved: net: tls: fix use-after-free with partial reads and async decrypt tlsdecryptsg doesn't take a reference on the pages from clearskb, so the putpage in tlsdecryptdone releases them, and we trigger a use-after-free in processrxlist...
