CVE-2026-90314: remoteproc: fix OOB read via signed offset in rsc_table_for_each_entry()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 0d385be8f199b349f325cf90584b47b6a044ea79, 6282d47b24b0c98d08d02807d676a7f67b4c052e, 6a01ad25aa4f3a02153cf1d112cb9b65865cd5d8; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1.

Low priority for now. Upgrade to Linux Linux 0d385be8f199b349f325cf90584b47b6a044ea79, 6282d47b24b0c98d08d02807d676a7f67b4c052e, 6a01ad25aa4f3a02153cf1d112cb9b65865cd5d8; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
