Overview

Affected versions of this package are vulnerable to Information Exposure in the restoration of SVE signal context when SME is supported. An attacker can cause the kernel to read out-of-bounds memory or place a task into an invalid state by manipulating the SVE signal context, such as modifying it in userspace or saving it in the context of another task. This is only exploitable if the SVE signal context has been altered by userspace or was saved from another task, or if ptrace is used to set SVCR.SM after entry to the sigreturn syscall.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
