Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2021-46955)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the ovs_fragment() function in net/openvswitch/actions.c when running openvswitch on kernels built with KASAN. A remote attacker can send specially crafted IPv4 packets to the system, trigger an out-of-bounds read error and read contents of memory on the system or crash the kernel.
2) Out-of-bounds read (CVE-ID: CVE-2021-47383)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to an out-of-bounds read error within the vc_do_resize() function in drivers/tty/vt/vt.c. A local user can perform a denial of service (DoS) attack.
3) 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.
4) 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.
5) 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.
6) Integer overflow (CVE-ID: CVE-2024-23307)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to integer overflow in raid5_cache_count() function. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.
7) 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.
8) 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.
9) Improper locking (CVE-ID: CVE-2024-26923)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper locking within the unix_gc() function in net/unix/garbage.c due to garbage collector does not take into account the risk of embryo getting enqueued during the garbage collection. A local user can execute arbitrary code with elevated privileges.
10) Double free (CVE-ID: CVE-2024-26930)
The vulnerability allows a local user to execute arbitrary code.
The vulnerability exists due to a double free error within the kfree() function in drivers/scsi/qla2xxx/qla_os.c. A local user can execute arbitrary code.
11) Use-after-free (CVE-ID: CVE-2024-27398)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the sco_sock_timeout() function in net/bluetooth/sco.c. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
12) Use-after-free (CVE-ID: CVE-2024-35950)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the drm_client_modeset_probe() function in drivers/gpu/drm/drm_client_modeset.c. A local user can escalate privileges on the system.
