CVE-2024-53189

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: nl80211: fix bounds checker error in nl80211_parse_sched_scan<br /> <br /> The channels array in the cfg80211_scan_request has a __counted_by<br /> attribute attached to it, which points to the n_channels variable. This<br /> attribute is used in bounds checking, and if it is not set before the<br /> array is filled, then the bounds sanitizer will issue a warning or a<br /> kernel panic if CONFIG_UBSAN_TRAP is set.<br /> <br /> This patch sets the size of allocated memory as the initial value for<br /> n_channels. It is updated with the actual number of added elements after<br /> the array is filled.
