This security bulletin contains information about 5 secuirty vulnerabilities.

1) Out-of-bounds read (CVE-ID: CVE-2022-48651)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in drivers/net/ipvlan/ipvlan_core.c. A remote attacker on the local network can send specially crafted packets to the system, trigger an out-of-bounds read error and read contents of memory on the system.

2) Use-after-free (CVE-ID: CVE-2023-1829)

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

The vulnerability exists due to a use-after-free error within the tcindex_delete() function. A local user can trigger a use-after-free error and execute arbitrary code with root privileges.

3) 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.

4) Race condition (CVE-ID: CVE-2023-6546)

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

The vulnerability exists due to a race condition in the GSM 0710 tty multiplexor in the Linux kernel. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.

5) Buffer overflow (CVE-ID: CVE-2024-26610)

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

The vulnerability exists due to a boundary error within the iwl_dbg_tlv_override_trig_node() function in drivers/net/wireless/intel/iwlwifi/iwl-dbg-tlv.c. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
