Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-1252)
The vulnerability allows a local authenticated user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. A local authenticated user can trigger a use-after-free error and escalate privileges on the system.
2) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2024-2201)
The vulnerability allows a malicious guest to escalate privileges on the system.
The vulnerability exists due to native branch history injection on x86 systems. A malicious guest can infer the contents of arbitrary host memory, including memory assigned to other guests and compromise the affected system.
3) Race condition (CVE-ID: CVE-2023-52489)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the section_deactivate() function in mm/sparse.c. A local user can exploit the race and escalate privileges on the system.
4) Buffer overflow (CVE-ID: CVE-2024-26671)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory corruption within the blk_mq_mark_tag_wait() function in block/blk-mq.c. A local user can perform a denial of service (DoS) attack.
5) Improper locking (CVE-ID: CVE-2024-26686)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the do_task_stat() function in fs/proc/array.c. A local user can perform a denial of service (DoS) attack.
6) Improper locking (CVE-ID: CVE-2024-26826)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the __mptcp_retransmit_pending_data() function in net/mptcp/protocol.c. A local user can perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2024-26961)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the mac802154_llsec_key_del_rcu() function in net/mac802154/llsec.c. A local user can escalate privileges on the system.
8) NULL pointer dereference (CVE-ID: CVE-2021-47384)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the TEMP_TO_REG() and w83793_detect_subclients() functions in drivers/hwmon/w83793.c. A local user can perform a denial of service (DoS) attack.
9) Use of uninitialized resource (CVE-ID: CVE-2024-36889)
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 mptcp_stream_connect() function in net/mptcp/protocol.c. A local user can perform a denial of service (DoS) attack.
10) NULL pointer dereference (CVE-ID: CVE-2024-40960)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the rt6_probe() function in net/ipv6/route.c. A local user can perform a denial of service (DoS) attack.
11) Improper locking (CVE-ID: CVE-2024-40998)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the __ext4_fill_super() function in fs/ext4/super.c. A local user can perform a denial of service (DoS) attack.
12) Use-after-free (CVE-ID: CVE-2024-41049)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the posix_lock_inode() function in fs/locks.c. A local user can escalate privileges on the system.
13) NULL pointer dereference (CVE-ID: CVE-2024-41055)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to NULL pointer dereference within the include/linux/mmzone.h. A local user can perform a denial of service (DoS) attack.
14) Improper locking (CVE-ID: CVE-2024-41064)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the eeh_pe_bus_get() function in arch/powerpc/kernel/eeh_pe.c. A local user can perform a denial of service (DoS) attack.
15) Memory leak (CVE-ID: CVE-2024-42152)
