6) Use-after-free (CVE-ID: CVE-2023-52840)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the rmi_unregister_function() function in drivers/input/rmi4/rmi_bus.c. A local user can escalate privileges on the system.
7) Resource exhaustion (CVE-ID: CVE-2024-12133)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources processing a large number of SEQUENCE OF or SET OF elements in a certificate. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
8) Resource exhaustion (CVE-ID: CVE-2024-12243)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to libtasn1 does not properly control consumption of internal resources when decoding certain DER-encoded certificate data. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
9) Information disclosure (CVE-ID: CVE-2024-26901)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to information disclosure within the do_sys_name_to_handle() function in fs/fhandle.c. A local user can perform a denial of service (DoS) attack.
10) 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.
11) Information disclosure (CVE-ID: CVE-2024-26973)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to information disclosure within the fat_encode_fh_nostale() function in fs/fat/nfs.c. A local user can gain access to sensitive information.
12) Improper locking (CVE-ID: CVE-2024-27013)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
