Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-48655)
The vulnerability allows a local user to execute arbitrary code.
The vulnerability exists due to an out-of-bounds read error within the scmi_domain_reset() function in drivers/firmware/arm_scmi/reset.c. A local user can execute arbitrary code.
2) Out-of-bounds write (CVE-ID: CVE-2024-36016)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the gsm0_receive() function in drivers/tty/n_gsm.c. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
3) Error handling (CVE-ID: CVE-2024-26584)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error when handling backlogging of crypto requests in net/tls/tls_sw.c. A remote attacker can send specially crafted traffic to the system and perform a denial of service attack.
4) Use-after-free (CVE-ID: CVE-2021-47131)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the tls_ctx_create() function in net/tls/tls_main.c, within the tls_validate_xmit_skb() function in net/tls/tls_device_fallback.c, within the tls_device_gc_task(), tls_device_rx_resync_new_rec(), tls_device_decrypted() and tls_device_down() functions in net/tls/tls_device.c. A local user can escalate privileges on the system.
5) Improper locking (CVE-ID: CVE-2024-26907)
The vulnerability allows a local user to execute arbitrary code.
The vulnerability exists due to improper locking within the set_eth_seg() function in drivers/infiniband/hw/mlx5/wr.c. A local user can execute arbitrary code.
6) 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.
7) 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.
