CVE-2026-98407: wifi: rsi: fix heap OOB write on key removal

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 00bea3589255603c38766cac4a4d6d36493b2556, 62d40db89180cfab7a917395f9ffc1dac62b0019, 8dab6ee020b2cd951b670626ba44a95cd4deac3d; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 00bea3589255603c38766cac4a4d6d36493b2556, 62d40db89180cfab7a917395f9ffc1dac62b0019, 8dab6ee020b2cd951b670626ba44a95cd4deac3d; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1 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: rsi: fix heap OOB write on key removal When a key is removed (data == NULL), rsi_hal_load_key() runs: memset(&set_key[FRAME_DESC_SZ], 0, frame_len - FRAME_DESC_SZ); set_key is a struct rsi_set_key *, so the subscript is scaled by sizeof(struct rsi_set_key) (160 bytes): &set_key[FRAME_DESC_SZ] is skb->data + 2560, and the memset writes 144 zero bytes starting 2.4KB past the end of the 160-byte skb data buffer, corrupting unrelated heap objects. The intended byte offset would have been (u8 *)set_key + FRAME_DESC_SZ. The write fires on every DISABLE_KEY callback, so plain disconnects, roams and interface teardowns trigger it on real networks. The memset is redundant: the whole buffer is zeroed right after allocation, so the frame sent to the device is byte-identical without it. Drop the else branch; normal operation is unaffected. Discovered by Atuin - Automated Vulnerability Discovery Engine.
