Descriptions
In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow.
En el kernel de Linux versiones hasta 5.3.2, la función cfg80211_mgd_wext_giwessid en el archivo net/wireless/wext-sme.c no rechaza un SSID IE largo, conllevando a un Desbordamiento de Búfer.
A vulnerability was found in the Linux kernel's generic WiFi ESSID handling implementation. The flaw allows a system to join a wireless network where the ESSID is longer than the maximum length of 32 characters, which can cause the system to crash or execute code.
Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle reference counting during memory mapping operations when used in conjunction with AUFS. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID lengths. A physically proximate attacker could use this to cause a denial of service. Various other issues were also addressed.
