Description

This security bulletin contains information about 4 vulnerabilities.


1) Improper locking (CVE-ID: CVE-2024-27415)

CWE-ID: CWE-667 - Improper Locking

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the nf_conntrack_init_end() function in net/netfilter/nf_conntrack_core.c, within the nf_ct_bridge_pre() function in net/bridge/netfilter/nf_conntrack_bridge.c, within the IS_ENABLED() and br_nf_pre_routing() functions in net/bridge/br_netfilter_hooks.c. A local user can perform a denial of service (DoS) attack.


2) Use-after-free (CVE-ID: CVE-2024-36979)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to a use-after-free error within the br_mst_vlan_set_state() and br_mst_set_state() functions in net/bridge/br_mst.c. A local user can escalate privileges on the system.


3) Input validation error (CVE-ID: CVE-2024-38558)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to insufficient validation of user-supplied input when parsing ICMPv6 packets within the parse_icmpv6() function in net/openvswitch/flow.c. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.


4) NULL pointer dereference (CVE-ID: CVE-2024-36270)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the nf_tproxy_laddr4() function in net/ipv4/netfilter/nf_tproxy_ipv4.c. A local user can perform a denial of service (DoS) attack.
