Last modified

CVE-2023-1380 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service.. EPSS estimates a 16.64% chance of exploitation in the next 30 days.
