CVE-2024-36957 is an out-of-bounds read in the Linux kernel OcteonTX2 AF driver. The affected code copied a userspace buffer with a requested length of count plus one byte in order to obtain a NUL-terminated buffer, despite userspace supplying and validating only count bytes. The fix replaces the copy operation with memdup_user_nul(), which copies the supplied length and safely appends a terminator.
