Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2021-47182)

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

The vulnerability exists due to a boundary error within the scsi_mode_sense() function in drivers/scsi/scsi_lib.c. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.


2) Memory leak (CVE-ID: CVE-2021-47199)

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

The vulnerability exists due to memory leak within the parse_tc_nic_actions() and parse_tc_fdb_actions() functions in drivers/net/ethernet/mellanox/mlx5/core/en_tc.c, within the mlx5_tc_ct_match_add(), mlx5_tc_ct_parse_action() and __mlx5_tc_ct_flow_offload_clear() functions in drivers/net/ethernet/mellanox/mlx5/core/en/tc_ct.c. A local user can perform a denial of service (DoS) attack.


3) NULL pointer dereference (CVE-ID: CVE-2021-47211)

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

The vulnerability exists due to a NULL pointer dereference error within the snd_usb_set_sample_rate_v2v3() function in sound/usb/clock.c. A local user can perform a denial of service (DoS) attack.


4) Race condition (CVE-ID: CVE-2023-52609)

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

The vulnerability exists due to a race condition within the binder_update_page_range() function in drivers/android/binder_alloc.c. A local user can escalate privileges on the system.


5) Memory leak (CVE-ID: CVE-2023-52610)

The vulnerability allows a local user to perform DoS attack on the target system.

The vulnerability exists due memory leak in net/sched/act_ct.c. A local user can force the kernel to leak memory and perform denial of service attack.


6) Improper Initialization (CVE-ID: CVE-2023-52616)

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

The vulnerability exists due to improper initialization within the mpi_ec_init() function in lib/mpi/ec.c. A local user can perform a denial of service (DoS) attack.


7) Buffer overflow (CVE-ID: CVE-2023-52618)

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

The vulnerability exists due to memory corruption within the rnbd_srv_get_full_path() function in drivers/block/rnbd/rnbd-srv.c. A local user can perform a denial of service (DoS) attack.


8) Use of uninitialized resource (CVE-ID: CVE-2024-26635)

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

The vulnerability exists due to use of uninitialized resource within the cpu_to_be16() function in net/llc/llc_core.c. A local user can perform a denial of service (DoS) attack.


9) Input validation error (CVE-ID: CVE-2024-26636)

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

The vulnerability exists due to improper input validation within the llc_ui_sendmsg() function in net/llc/af_llc.c. A local user can perform a denial of service (DoS) attack.


10) Resource management error (CVE-ID: CVE-2024-26640)

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

The vulnerability exists due to improper management of internal resources within the skb_advance_to_frag() function in net/ipv4/tcp.c. A remote attacker can send specially crafted data to the system and perform a denial of service (DoS) attack.


11) Access of Uninitialized Pointer (CVE-ID: CVE-2024-26641)

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

The vulnerability exists due to access to uninitialized data within the __ip6_tnl_rcv() function in net/ipv6/ip6_tunnel.c. A remote attacker can send specially crafted data to the system and perform a denial of service (DoS) attack.


12) Incorrect calculation (CVE-ID: CVE-2024-26752)

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

The vulnerability exists due to incorrect calculation within the l2tp_ip6_sendmsg() function in net/l2tp/l2tp_ip6.c. A local user can perform a denial of service (DoS) attack.


13) Off-by-one (CVE-ID: CVE-2024-26766)

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

The vulnerability exists due to an off-by-one error within the _pad_sdma_tx_descs() function in drivers/infiniband/hw/hfi1/sdma.c. A local user can trigger an off-by-one error and execute arbitrary code with elevated privileges.
