kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

By exploiting the RDS TCP transport SORDSTRANSPORT=2 in conjunction with iouring, a local unprivileged attacker can cause memory corruption a...

kernel: Read root-owned files as an unprivileged user

A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Firmware: armscpi: Fixed string overflow in the SCPI genpd driver. Without the bounds checks for scpipd-name, a buffer overflow could occur when copying the SCPI device name from the corresponding device tree node. This occurs...
