This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.\n (CVE-2022-0168)\n\n - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub- component. This flaw allows a local attacker with a user privilege to cause a denial of service.\n (CVE-2022-1184)\n\n - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. (CVE-2022-1652)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data.
