Doc Text:	An out-of-bounds vulnerability was found in the Linux kernel in the mwifiex_process_rx_packet() function which occurs from improper boundary checks when accessing the RFC1042 headers in received packets. If the packet buffer is too small the function skips code paths that handle these headers which could lead to incorrect packet processing and a potential out-of-bounds access, causing a crash or memory corruption.

Comment 1 Alex 2024-06-09 15:28:49 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2023-52525 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags REMOTE OOB SIMPLEFIX SKB  ; these flags parsed automatically based on patche data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
