CVE-2026-98188: wifi: p54: validate curve data length in the calibration curve converters

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: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 03d313e3dfb49a44c10a5c423452967694fb85e2, 3bdcc4d61212b001b8752d80036509b4974ce16c, 41cdf14bf4b52fbe4673a172c2a6ad756cb08111; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1.

Low priority for now. Upgrade to Linux Linux 03d313e3dfb49a44c10a5c423452967694fb85e2, 3bdcc4d61212b001b8752d80036509b4974ce16c, 41cdf14bf4b52fbe4673a172c2a6ad756cb08111; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: p54: validate curve data length in the calibration curve converters p54_convert_rev0() and p54_convert_rev1() read calibration curve data from the device-supplied EEPROM entry using channel and points-per-channel counts taken verbatim from that same entry, so an entry that declares more data than it carries drives an out-of-bounds read past the EEPROM buffer (verified with a KASAN reproducer of the conversion loop). The sibling converters p54_convert_output_limits() and p54_convert_db() already validate their counts against the entry length; this path was missed. Reject the entry when the counts do not fit in the entry data.
