CVE-2025-38524

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix recv-recv race of completed call If a call receives an event such as incoming data, the call gets placed on the socket's queue and a thread in recvmsg can be awakened to go and process it. Once the thread has picked up...

Linux kernel 安全漏洞

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 the net/smc module not properly checking the return value of sockrecvmsg when receiving a clc message, which...

kernel: tls: get psock ref after taking rxlock to avoid leak

In the Linux kernel, the following vulnerability has been resolved: tls: get psock ref after taking rxlock to avoid leak At the start of tlsswrecvmsg, we take a reference on the psock, and then call tlsrxreaderlock. If that fails, we return directly without releasing the reference. Instead of...

SUSE CVE-2024-42076

In the Linux kernel, the following vulnerability has been resolved: net: can: j1939: Initialize unused data in j1939sendone syzbot reported kernel-infoleak in rawrecvmsg 1. j1939sendone creates full frame including unused data, but it doesn't initialize it. This causes the kernel-infoleak issue...

kernel: use-after-free in net/atm/ioctl.c

A use-after-free flaw was found in the Linux kernel's net/atm/ioctl.c ATM networking technology driver: dovccioctl in net/atm/ioctl.c is vulnerable to use-after-free due to a race condition in vccrecvmsg. This issue can allow an attacker to possibly gain unauthorized access, escalate privileges, ...
