https://notcve.org/view.php?id=CVE-2022-41674
An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c. Se ha detectado un problema en el kernel de Linux versiones hasta 5.19.11. Los atacantes capaces de inyectar tramas WLAN podrían causar un desbordamiento del búfer en la función ieee80211_bss_info_update en el archivo net/mac80211/scan.c A buffer overflow flaw was found in the u8 overflow in cfg80211_update_notlisted_nontrans() in net/wireless/scan.c in the Linux kernel’s wifi subcomponent. This flaw allows an attacker to crash the system or leak internal kernel information. • http://packetstormsecurity.com/files/169951/Kernel-Live-Patch-Security-Notice-LSN-0090-1.html http://www.openwall.com/lists/oss-security/2022/10/13/2 https://bugzilla.suse.com/show_bug.cgi?id=1203770 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/net/mac80211/scan.c https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless.git/commit/?id=aebe9f4639b13a1f4e9a6b42cdd2e38c617b442d https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https: • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

An issue was discovered in Dropbear through 2020.81. Due to a non-RFC-compliant check of the available authentication methods in the client-side SSH code, it is possible for an SSH server to change the login process in its favor. This attack can bypass additional security measures such as FIDO2 tokens or SSH-Askpass. Thus, it allows an attacker to abuse a forwarded agent for logging on to another server unnoticed. Se ha detectado un problema en Dropbear versiones hasta 2020.81. • https://github.com/mkj/dropbear/pull/128 https://github.com/mkj/dropbear/releases https://github.com/mkj/dropbear/releases/tag/DROPBEAR_2022.82 https://lists.debian.org/debian-lts-announce/2022/11/msg00015.html • CWE-287: Improper Authentication •
