CVE-2025-39761: wifi: ath12k: Decrement TID on RX peer frag setup error handling

HighCVSS 7.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.24% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 7c0884fcd2ddde0544d2e77f297ae461e1f53f58, 7c3e99fd4a66a5ac9c7dd32db07359666efe0002, 9530d666f4376c294cdf4348c29fe3542fec980a.

Low priority for now. Upgrade to Linux Linux 7c0884fcd2ddde0544d2e77f297ae461e1f53f58, 7c3e99fd4a66a5ac9c7dd32db07359666efe0002, 9530d666f4376c294cdf4348c29fe3542fec980a 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: ath12k: Decrement TID on RX peer frag setup error handling Currently, TID is not decremented before peer cleanup, during error handling path of ath12k_dp_rx_peer_frag_setup(). This could lead to out-of-bounds access in peer->rx_tid[]. Hence, add a decrement operation for TID, before peer cleanup to ensures proper cleanup and prevents out-of-bounds access issues when the RX peer frag setup fails. Found during code review. Compile tested only.
