An issue was found in Linux kernel before 5.5.4. mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy, aka CID-3a9b153c5591. Se detectó un problema en el kernel de Linux versiones anteriores a 5.5.4. En la función mwifiex_ret_wmm_get_status() en el archivo drivers/net/wireless/marvell/mwifiex/wmm.c permite a un AP remoto desencadenar un desbordamiento del búfer en la región heap de la memoria debido a una memcpy incorrecta, también se conoce como CID-3a9b153c5591. A flaw was found in the Linux kernel. The Marvell mwifiex driver allows a remote WiFi access point to trigger a heap-based memory buffer overflow due to an incorrect memcpy operation. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://www.openwall.com/lists/oss-security/2020/05/08/2 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.5.4 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3a9b153c5591548612c3955c9600a98150c81875 https://github.com/torvalds/linux/commit/3a9b153c5591548612c3955c9600a98150c81875 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
