CVE-2026-23288 Details
Description
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.
A vulnerability in the Linux kernel's handling of command slots for AMD DNA acceleration can lead to an out-of-bounds write and memory corruption. This issue arises because the remaining space in a command slot may be smaller than the command header size. The vulnerability has been addressed by modifying the order of operations: the command header is now cleared after verifying the available slot space, rather than before, which prevents the out-of-bounds write.
