CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2024-53189
Medium (5.5) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.
In 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.
