CVE-2026-89858: scsi: qla2xxx: Bound image count in qla2x00_update_fru_versions()

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 047f1f7ee6f85bde28abfdda9fa550191ddc0532, 7b22b4cb8822805cef7ba618da6f76e1474d68bd, 7e3154c97ec15460f715dbbe4097c255cce110b1; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 047f1f7ee6f85bde28abfdda9fa550191ddc0532, 7b22b4cb8822805cef7ba618da6f76e1474d68bd, 7e3154c97ec15460f715dbbe4097c255cce110b1; 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: scsi: qla2xxx: Bound image count in qla2x00_update_fru_versions() qla2x00_update_fru_versions() copies the user-supplied BSG request into a fixed 256-byte stack buffer (bsg[DMA_POOL_SIZE]) and then iterates list->count times over the qla_image_version array embedded in that buffer, advancing the image pointer each iteration. count is taken directly from user input with no upper bound, while only (DMA_POOL_SIZE - sizeof(list->count)) / sizeof(struct qla_image_version) = 6 entries actually fit. A larger count walks the image pointer off the end of the stack buffer, reading adjacent kernel stack memory and sending it to the device via qla2x00_write_sfp(). Reject requests whose declared count does not fit in the buffer.
