CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-31083
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the hci_uart_tty_ioctl() function in drivers/bluetooth/hci_ldisc.c. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
MitigationUpdate the affected package linux to the latest version.

CVE-ID: CVE-2023-38430
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in ksmbd when handling SMB request protocol ID. A remote attacker can send specially crafted packets to the system to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.

CVE-ID: CVE-2023-3865
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the ksmbd_smb2_check_message() function in fs/smb/server/smb2misc.c when parsing smb2_hdr structure. A remote user can send specially crafted packets to ksmbd, trigger an out-of-bounds read error and read contents of memory or perform a denial of service (DoS) attack.

CVE-ID: CVE-2023-44466
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ceph_decode_32() function in net/ceph/messenger_v2.c in the Ceph filesystem when handling TCP packets. A remote attacker can send specially crafted HELLO or AUTH frames to trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
