CVE-2024-47712: wifi: wilc1000: fix potential RCU dereference issue in wilc_parse_join_bss_param

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.36% (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 2f944e6255c2fc1c9bd9ee32f6b14ee0b2a51eb5, 5.10.227, 5.15.168; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5.
  • Severity is disputed: the assigning authority (CNA) scores it 8.3, NVD 5.5.

Low priority for now. Upgrade to Linux Linux 2f944e6255c2fc1c9bd9ee32f6b14ee0b2a51eb5, 5.10.227, 5.15.168; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: fix potential RCU dereference issue in wilc_parse_join_bss_param In the `wilc_parse_join_bss_param` function, the TSF field of the `ies` structure is accessed after the RCU read-side critical section is unlocked. According to RCU usage rules, this is illegal. Reusing this pointer can lead to unpredictable behavior, including accessing memory that has been updated or causing use-after-free issues. This possible bug was identified using a static analysis tool developed by myself, specifically designed to detect RCU-related issues. To address this, the TSF value is now stored in a local variable `ies_tsf` before the RCU lock is released. The `param->tsf_lo` field is then assigned using this local variable, ensuring that the TSF value is safely accessed.
