Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2024-36886)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a use-after-free error within the tipc_buf_append() function in net/tipc/msg.c when processing fragmented TIPC messages. A remote attacker can send specially crafted packets to the system, trigger a use-after-free error and execute arbitrary code on the system in the context of the kernel.
2) Buffer overflow (CVE-ID: CVE-2021-47548)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to memory corruption within the hns_dsaf_ge_srst_by_port() function in drivers/net/ethernet/hisilicon/hns/hns_dsaf_misc.c. A local user can escalate privileges on the system.
3) Use-after-free (CVE-ID: CVE-2021-47596)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the hclgevf_send_mbx_msg() function in drivers/net/ethernet/hisilicon/hns3/hns3vf/hclgevf_mbx.c. A local user can escalate privileges on the system.
4) Resource exhaustion (CVE-ID: CVE-2022-48627)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Improper locking (CVE-ID: CVE-2023-52638)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the j1939_jsk_add(), j1939_sk_recv_match(), j1939_sk_recv(), j1939_sk_errqueue() and j1939_sk_netdev_event_netdown() functions in net/can/j1939/socket.c, within the j1939_netdev_start() function in net/can/j1939/main.c. A local user can perform a denial of service (DoS) attack.
6) Race condition (CVE-ID: CVE-2024-26583)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition between async notify and socket close in TLS implementation in net/tls/tls_sw.c. A remote attacker can send specially crafted traffic to the system, trigger a race condition and perform a denial of service (DoS) attack.
7) Race condition (CVE-ID: CVE-2024-26585)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition within the tls_encrypt_done() function in net/tls/tls_sw.c. A remote attacker user can send specially crafted requests to the system and perform a denial of service (DoS) attack.
8) Division by zero (CVE-ID: CVE-2024-26720)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a division by zero error within the wb_dirty_limits() function in mm/page-writeback.c. A local user can perform a denial of service (DoS) attack.
9) Resource management error (CVE-ID: CVE-2024-26783)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to resource management error within the numamigrate_isolate_page() function in mm/migrate.c. A local user can perform a denial of service (DoS) attack.
10) Use-after-free (CVE-ID: CVE-2024-26801)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the hci_error_reset() function in net/bluetooth/hci_core.c. A local user can escalate privileges on the system.
11) 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.
12) NULL pointer dereference (CVE-ID: CVE-2024-35857)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the icmp_build_probe() function in net/ipv4/icmp.c. A local user can perform a denial of service (DoS) attack.
13) Race condition within a thread (CVE-ID: CVE-2024-35898)
The vulnerability allows a local user to manipulate data.
The vulnerability exists due to a data race within the nf_tables_flowtable_parse_hook() and nft_flowtable_type_get() functions in net/netfilter/nf_tables_api.c. A local user can manipulate data.
14) Use-after-free (CVE-ID: CVE-2024-35969)
The vulnerability allows a local user to escalate privileges on the system.
