CVE-2026-90314

/// Technical description

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.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
