In the Linux kernel, the following vulnerability has been resolved: media: vidtv: mux: Added checks and calls to kstrdup. A check is performed on the return value of kstrdup; if it fails, an error is returned to avoid NULL pointer dereferencing. Additionally, kfree is used in the subsequent error...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: IB/mlx5: Fixed error handling during the init stage to avoid double-freeing of the same QP and UAF. In the unlikely event that workqueue allocation fails and returns NULL in mlx5mkeycacheinit, delete the call to...
