Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-1252)
The vulnerability allows a local authenticated user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. A local authenticated user can trigger a use-after-free error and escalate privileges on the system.
2) Buffer overflow (CVE-ID: CVE-2024-35884)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory corruption within the udp_gro_receive() function in net/ipv4/udp_offload.c, within the __udp_is_mcast_sock() function in net/ipv4/udp.c. A local user can perform a denial of service (DoS) attack.
3) Use-after-free (CVE-ID: CVE-2021-47321)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the wdt_startup() function in drivers/watchdog/w83877f_wdt.c, within the lpc18xx_wdt_remove() function in drivers/watchdog/lpc18xx_wdt.c. A local user can escalate privileges on the system.
4) NULL pointer dereference (CVE-ID: CVE-2021-47560)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the mlxsw_sp_pude_event_func() function in drivers/net/ethernet/mellanox/mlxsw/spectrum.c. A local user can perform a denial of service (DoS) attack.
5) Off-by-one (CVE-ID: CVE-2024-36025)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an off-by-one error within the qla_edif_app_getstats() function in drivers/scsi/qla2xxx/qla_edif.c. A local user can perform a denial of service (DoS) attack.
6) Race condition (CVE-ID: CVE-2024-36952)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the lpfc_vport_delete() function in drivers/scsi/lpfc/lpfc_vport.c. A local user can escalate privileges on the system.
7) Input validation error (CVE-ID: CVE-2024-38558)
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.
8) Improper locking (CVE-ID: CVE-2024-39476)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the raid5d() function in drivers/md/raid5.c. A local user can perform a denial of service (DoS) attack.
9) Improper locking (CVE-ID: CVE-2024-40998)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the __ext4_fill_super() function in fs/ext4/super.c. A local user can perform a denial of service (DoS) attack.
10) Use-after-free (CVE-ID: CVE-2024-41040)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the net/sched/act_ct.c. A local user can escalate privileges on the system.
11) Buffer overflow (CVE-ID: CVE-2024-42284)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to memory corruption within the tipc_udp_addr2str() function in net/tipc/udp_media.c. A local user can escalate privileges on the system.
