Description
This security bulletin contains information about 18 secuirty vulnerabilities.
1) Improper Check for Unusual or Exceptional Conditions (CVE-ID: CVE-2023-52429)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper error handling within the dm_table_create() function in drivers/md/dm-table.c. A local user can pass specially crafted data to the kernel and perform a denial of service (DoS) attack.
2) Buffer overflow (CVE-ID: CVE-2023-52434)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the smb2_parse_contexts() function when parsing SMB packets. A remote user can send specially crafted SMB traffic to the affected system, trigger memory corruption and execute arbitrary code.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Buffer overflow (CVE-ID: CVE-2023-52435)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the skb_segment() function. A local user can trigger memory corruption and crash the kernel.
4) 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.
5) Improper Initialization (CVE-ID: CVE-2024-0340)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to improper initialization within the vhost_new_msg() function in drivers/vhost/vhost.c in the Linux kernel vhost driver. A local user can run a specially crafted application to gain access to sensitive kernel information.
6) NULL pointer dereference (CVE-ID: CVE-2024-0841)
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 hugetlbfs_fill_super() function in the Linux kernel hugetlbfs (HugeTLB pages) functionality. A local user can perform a denial of service (DoS) attack.
7) Stack-based buffer overflow (CVE-ID: CVE-2024-1151)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the Open vSwitch sub-component in the Linux Kernel. A remote unauthenticated attacker can send specially crafted packets to the system. trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.
8) Race condition (CVE-ID: CVE-2024-2193)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a speculative race condition. A local user can exploit the race and gain unauthorized access to contents of arbitrary host memory, including memory assigned to other guests.
The vulnerability was dubbed GhostRace.
9) Reachable Assertion (CVE-ID: CVE-2024-23850)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion within the btrfs_get_root_ref() function in fs/btrfs/disk-io.c. A local user can perform a denial of service (DoS) attack.
10) Out-of-bounds read (CVE-ID: CVE-2024-23851)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the copy_params() function in drivers/md/dm-ioctl.c. A remote attacker can trigger an out-of-bounds read and perform a denial of service (DoS) attack.
11) Input validation error (CVE-ID: CVE-2024-26581)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in net/netfilter/nft_set_rbtree.c. A locla user can perform a denial of service (DoS) attack.
12) Use-after-free (CVE-ID: CVE-2024-26582)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in net/tls/tls_sw.c during partial reads and async decrypt. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.
13) 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.
14) Improper locking (CVE-ID: CVE-2024-26601)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the ext4_mb_generate_buddy() and mb_free_blocks() functions in fs/ext4/mballoc.c. A local user can perform a denial of service (DoS) attack.
15) Resource exhaustion (CVE-ID: CVE-2024-26602)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
