In the Linux kernel, the following vulnerability has been resolved: pinctrl: ralink: Check for a null return from devmkcalloc. Due to the potential failure of the allocation, data-domains might be a NULL pointer, and this could lead to the dereferencing of a NULL pointer later. Therefore, it migh...

Astra Linux – Vulnerability in Linux, Linux 5.10

A data leak flaw was discovered in the way of the XFSIOCALLOCSP IOCTL in the XFS filesystem, which allows for an increase in file sizes when the size is unaligned. A local attacker could exploit this flaw to leak data from the XFS filesystem that would otherwise be inaccessible to them...
