QID 354008

Due to the small table perturb size, a memory leak flaw was found in the linux kernel's tcp source port generation algorithm in the net/ipv4/tcp.c function.
This flaw allows an attacker to leak information and may cause a denial of service. (
( CVE-2022-1012) 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. (
( CVE-2022-1184) a use-after-free vulnerability was found in the linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.
This flaw allows a local attacker with user access to cause a privilege escalation issue. (
( CVE-2022-1966) kgdb and kdb allow read and write access to kernel memory, and thus should be restricted during lockdown.
An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered.
Cvss 3.1 base score 6.5 (confidentiality, integrity and availability impacts).
Cvss vector: (cvss:3.1/av:l/ac:l/pr:h/ui:r/s:u/c:h/i:h/a:h). (
( CVE-2022-21499) net/netfilter/nf_tables_api.c in the linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect nft_stateful_expr check leads to a use-after-free. (
( CVE-2022-32250) the linux kernel before 5.17.9 allows tcp servers to identify clients by observing what source ports are used. (
( CVE-2022-32296) an issue was discovered in the linux kernel through 5.18.3 on powerpc 32-bit platforms.
There is a buffer overflow in ptrace peekuser and pokeuser (aka peekusr and pokeusr) when accessing floating point registers. (
( CVE-2022-32981)

Successful exploitation of this vulnerability could lead to a securitybreach or could affect integrity, availability, and confidentiality.
