DEBIAN-CVE-2024-47712
No affected components available
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.
