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) 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.


3) Integer underflow (CVE-ID: CVE-2024-26828)

The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to integer underflow within the parse_server_interfaces() function in fs/smb/client/smb2ops.c. A local user can execute arbitrary code.


4) Use-after-free (CVE-ID: CVE-2024-26852)

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

The vulnerability exists due to a use-after-free error within the ip6_route_multipath_add() and list_for_each_entry_safe() functions in net/ipv6/route.c. A local user can escalate privileges on the system.


5) Improper locking (CVE-ID: CVE-2024-26923)
