CVE-2026-63967
Description
A flaw was found in the Linux kernel's st_lsm6dsx driver. This vulnerability occurs in the tagged FIFO (First-In, First-Out) buffer path, where a buffer on the stack is not properly initialized. A local attacker could exploit this by reading uninitialized memory from the kernel stack, leading to information disclosure.
