CVE-2026-90295: cpufreq: imx6q: fix out-of-bounds write when probed more than once

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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 263a35331169390f7f9ccb51d74e668610199af4, 49f2f9b1d0cc76cf221306fc707703205bd27073, 55516986a3d81325c84f2d4ae9cd03116bc63599; 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 263a35331169390f7f9ccb51d74e668610199af4, 49f2f9b1d0cc76cf221306fc707703205bd27073, 55516986a3d81325c84f2d4ae9cd03116bc63599; 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: cpufreq: imx6q: fix out-of-bounds write when probed more than once imx6_soc_volt is allocated fresh on every probe, sized to the number of ARM OPPs: imx6_soc_volt = devm_kcalloc(cpu_dev, num, sizeof(*imx6_soc_volt), GFP_KERNEL); but it is filled through soc_opp_count, which has static storage and is never reset. A second bind after an unbind keeps indexing from where the first one stopped, and writes past the end of the new array. Unbinding and rebinding the driver on qemu's mcimx6ul-evk, under KASAN: BUG: KASAN: slab-out-of-bounds in imx6q_cpufreq_probe+0x3b0/0xa34 Write of size 4 at addr c5e90480 by task binder/73 imx6q_cpufreq_probe from platform_probe+0x88/0xe4 platform_probe from really_probe+0x108/0x384 bind_store from kernfs_fop_write_iter+0x1b4/0x28c The write lands one u32 past the end of the allocation. soc_opp_count is only read a few lines below the loop that fills it, so it never needed static storage. Make it a local.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Bug bounty scope

No known public program.

Source: bounty-targets-data (public HackerOne, Bugcrowd, Intigriti, YesWeHack listings).

Technical details

No CVSS vector for this record, so attack conditions can't be derived.

Weakness class (CWE)

Attack context

MITRE CAPEC attack patterns and ATT&CK techniques for this weakness class (CWE). A starting point for detection rules and threat hunting.
