7) Buffer overflow (CVE-ID: CVE-2024-36920)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability exists due to memory corruption within the mpi3mr_bsg_process_mpt_cmds() function in drivers/scsi/mpi3mr/mpi3mr_app.c. A local user can perform a denial of service (DoS) attack.

8) NULL pointer dereference (CVE-ID: CVE-2024-36901)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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

The vulnerability exists due to NULL pointer dereference within the ip6_output() function in net/ipv6/ip6_output.c. A local user can perform a denial of service (DoS) attack.

9) Improper neutralization of directives in statically saved code (\'static code injection\') (CVE-ID: CVE-2024-42084)

CWE-ID: CWE-96 - Improper Neutralization of Directives in Statically Saved Code (\'Static Code Injection\')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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

In the Linux kernel, the following vulnerability has been resolved: ftruncate: pass a signed offset The old ftruncate() syscall, using the 32-bit off_t misses a sign extension when called in compat mode on 64-bit architectures. As a result, passing a negative length accidentally succeeds in truncating to file size between 2GiB and 4GiB. Changing the type of the compat syscall to the signed compat_off_t changes the behavior so it instead returns -EINVAL. The native entry point, the truncate() syscall and the corresponding loff_t based variants are all correct already and do not suffer from this mistake.

10) Input validation error (CVE-ID: CVE-2024-42265)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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

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

11) Out-of-bounds read (CVE-ID: CVE-2025-21785)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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

The vulnerability exists due to an out-of-bounds read error within the populate_cache_leaves() function in arch/arm64/kernel/cacheinfo.c. A local user can perform a denial of service (DoS) attack.
