CVE-2026-23288: Linux kernel out-of-bounds read vulnerability

Linux · Linux Kernel

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix out-of-bounds memset in command slot handling The remaining space in a command slot may be smaller than the size of the command header. Clearing the command header with memset() before verifying the available slot space can result in an out-of-bounds write and memory corruption. Fix this by moving the memset() call after the size validation.
