USN-8875-1: Linux kernel vulnerabilities
Ubuntu patches Linux kernel flaws, including a local null-pointer crash in the i.MX clock driver (CVE-2022-3114).
Ubuntu published USN-8875-1 to fix multiple Linux kernel vulnerabilities. CVE-2022-3114 is a null-pointer dereference in the i.MX clock driver: a local attacker who triggers a memory-allocation failure could crash the system. The update also addresses issues in UAPI, several CPU architectures, User-Mode Linux, the block layer, and the cryptographic API. Ubuntu warns some flaws could be used to compromise a system; exploitation is not described as observed.
- USN-8875-1 covers multiple Linux kernel flaws across architectures and subsystems.
- CVE-2022-3114 is a local null-pointer dereference in the i.MX clock driver that can crash the system.
- Ubuntu says an attacker could possibly use other fixed issues to compromise the system.
- No exploitation in the wild is reported.

It was discovered that the i.MX clock driver in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-3114) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - User-space API (UAPI); - ARM32 architecture; - ARM64 architecture; - MIPS architecture; - PowerPC architecture; - RISC-V architecture; - User-Mode Linux (UML); - x86 architecture; - Block layer subsystem; - Cryptographic API; -…
