The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the mac80211 stack in Linux kernel when parsing a multi-BSS element. A remote attacker on the local network can send specially crafted WLAN frames to the affected system, trigger a use-after-free error and execute arbitrary code.

87) Buffer overflow (CVE-ID: CVE-2022-42721)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a list management error in the mac80211 stack in the Linux kernel when handling BSS. A remote attacker on the local network can send specially crafted WLAN frames to the system, trigger linked list corruption and execute arbitrary code.

88) NULL pointer dereference (CVE-ID: CVE-2022-42722)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the mac80211 stack in Linux kernel. A remote attacker on the local network can send specially crafted WLAN frames to the affected system and perform a denial of service (DoS) attack against the beacon protection of P2P devices.

89) Access of Uninitialized Pointer (CVE-ID: CVE-2022-42895)

The vulnerability allows an attacker to gain access to sensitive information.

The vulnerability exists due to unauthorized access of uninitialized pointer within the l2cap_parse_conf_req() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to the affected device can gain access to sensitive information.

90) Use-after-free (CVE-ID: CVE-2022-42896)

The vulnerability allows an attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the l2cap_connect() and l2cap_le_connect_req() function in net/bluetooth/l2cap_core.c. An attacker with physical proximity to the affected device can trigger a use-after-free error and execute arbitrary code on the system.

91) Out-of-bounds write (CVE-ID: CVE-2022-43750)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

92) Stack-based buffer overflow (CVE-ID: CVE-2022-4378)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the __do_proc_dointvec() function. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.

93) Buffer overflow (CVE-ID: CVE-2022-43945)

The vulnerability allows a remote attacker to perform a denial of service attacl.

The vulnerability exists due to a boundary error within the Linux kernel NFSD implementation. A remote attacker can send the RPC message over TCP with garbage data added at the end of the message, trigger memory corruption and perform a denial of service (DoS) attack.

94) Race condition (CVE-ID: CVE-2022-45869)

The vulnerability allows a remote user to escalate privileges on the system.

The vulnerability exists due to a race condition within the x86 KVM subsystem in the Linux kernel when nested virtualisation and the TDP MMU are enabled. A remote  user on the guest OS can exploit the race and crash the host OS.

95) Race condition (CVE-ID: CVE-2022-45888)

The vulnerability allows an attacker to escalate privileges on the system.

The vulnerability exists due to a race condition within the drivers/char/xillybus/xillyusb.c in Linux kernel. An attacker with physical access to the system can trigger a use-after-free error during physical removal of a USB device and execute arbitrary code.

96) Integer overflow (CVE-ID: CVE-2022-45934)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow within the l2cap_config_req() function in net/bluetooth/l2cap_core.c in Linux kernel. A local user can pass specially crafted L2CAP_CONF_REQ packets to the device, trigger an integer overflow and execute arbitrary code with elevated privileges.
