GHSA-QW2P-M25F-7RCR
Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-10-08 15:32In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: fix bounds checker error in nl80211_parse_sched_scan
The channels array in the cfg80211_scan_request has a __counted_by attribute attached to it, which points to the n_channels variable. This attribute is used in bounds checking, and if it is not set before the array is filled, then the bounds sanitizer will issue a warning or a kernel panic if CONFIG_UBSAN_TRAP is set.
This patch sets the size of allocated memory as the initial value for n_channels. It is updated with the actual number of added elements after the array is filled.
