Summary
It was discovered that the UDF file system implementation in the Linux
kernel could attempt to dereference a null pointer in some situations. An
attacker could use this to construct a malicious UDF image that, when
mounted and operated on, could cause a denial of service (system crash).
(CVE-2022-0617)
Lyu Tao discovered that the NFS implementation in the Linux kernel did not
properly handle requests to open a directory on a regular file. A local
attacker could use this to expose sensitive information (kernel memory).
(CVE-2022-24448)
It was discovered that the YAM AX.25 device driver in the Linux kernel did
not properly deallocate memory in some error conditions. A local privileged
attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2022-24959)
