NewCVE-2026-90314 (opens in a new tab)How to fix?
Upgrade Debian:12 linux-6.12 to version 6.12.111-1~deb12u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: fix OOB read via signed offset in rsc_table_for_each_entry()
table->offset[i] is a u32 from firmware, but was stored into a signed int. A crafted offset like 0xFFFFFFF0 becomes -16, placing hdr 16 bytes before the table buffer. The subsequent avail check was bypassed because the negative int was promoted to a large size_t in the expression "table_sz - offset - sizeof(*hdr)", yielding a large positive avail and letting the out-of-bounds hdr->type read proceed undetected.
Store the offset as u32 and validate it with unsigned comparisons before any pointer arithmetic.
