Summary: Several security issues were fixed in the Linux kernel.
Jann Horn discovered that the Linux kernel did not properly track memory
allocations for anonymous VMA mappings in some situations, leading to
potential data structure reuse. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-42703)
It was discovered that the video4linux driver for Empia based TV cards in
the Linux kernel did not properly perform reference counting in some
situations, leading to a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-3239)

Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the NFSD implementation in the Linux kernel did not
properly handle some RPC messages, leading to a buffer overflow. A remote
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2022-43945)
It was discovered that a memory leak existed in the IPv6 implementation of
the Linux kernel. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2022-3524)
It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or

CVE-2022-3621 [MEDIUM] CWE-476 kernel: nilfs2: NULL pointer dereference in nilfs_bmap_lookup_at_level in fs/nilfs2/inode.c
kernel: nilfs2: NULL pointer dereference in nilfs_bmap_lookup_at_level in fs/nilfs2/inode.c
A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function nilfs_bmap_lookup_at_level of the file fs/nilfs2/inode.c of the component nilfs2. The manipulation leads to null pointer dereference. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211920.
A flaw was found in the NILFS2 file system implementation in the Linux kernel. If the i_mode field in inode of the metadata files is corrupted on the disk, it can cause the initialization of the bmap structure not being called, resulting in a NULL pointer dereference at nilfs_bmap_lookup_at_level.
