Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Race condition (CVE-ID: CVE-2023-51780)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the ATM (Asynchronous Transfer Mode) subsystem in Linux kernel. A local user can exploit the race and escalate privileges on the system.
2) Race condition (CVE-ID: CVE-2023-51781)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the Appletalk subsystem in Linux kernel. A local user can exploit the race and escalate privileges on the system.
3) Race condition (CVE-ID: CVE-2023-51782)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the Amateur Radio X.25 PLP (Rose) support. A local user can exploit the race and escalate privileges on the system.
4) Out-of-bounds read (CVE-ID: CVE-2023-6121)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the NVMe-oF/TCP subsystem in the Linux kernel. A remote attacker can send specially crafted data to the system, trigger an out-of-bounds read error and read contents of memory.
5) Race condition (CVE-ID: CVE-2023-6531)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition when the unix garbage collector's deletion of a SKB races with unix_stream_read_generic() on the socket that the SKB is queued on. A local user can exploit the race and escalate privileges on the system.
6) NULL pointer dereference (CVE-ID: CVE-2023-6622)
The 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 nft_dynset_init() function in net/netfilter/nft_dynset.c in nf_tables. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2023-6932)
The vulnerability allows a local authenticated user to execute arbitrary code.
The vulnerability exists due to a use-after-free error within the ipv4 igmp component in Linux kernel. A local authenticated user can trigger a use-after-free error and execute arbitrary code.
8) Integer underflow (CVE-ID: CVE-2024-0565)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow within the receive_encrypted_standard() function in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. A remote attacker can trick the victim to connect to a malicious SMB server, trigger an integer underflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Resource management error (CVE-ID: CVE-2024-0607)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the nft_byteorder_eval() function in the Netfilter subsystem. A local user can perform a denial of service (DoS) attack.
10) Out-of-bounds write (CVE-ID: CVE-2024-0646)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input in the Linux kernel’s Transport Layer Security functionality in the way a user calls a function splice with a ktls socket as the destination. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
11) Out-of-bounds read (CVE-ID: CVE-2024-22705)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the smb2_get_data_area_len() function in fs/smb/server/smb2misc.c in Linux kernel ksmbd. A local user can trigger an out-of-bounds read error and read contents of memory on the system.
