AlmaLinux 8 : kernel (ALSA-2022:0825)

high Nessus Plugin ID 179417

Synopsis

The remote AlmaLinux host is missing one or more security updates.

Description

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2022:0825 advisory.

- In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
Upstream kernel (CVE-2021-0920)

- A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.
(CVE-2021-4154)

- A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-0330)

- A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network. (CVE-2022-0435)

- A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
(CVE-2022-0492)

- A vulnerability was found in kvm_s390_guest_sida_op in the arch/s390/kvm/kvm-s390.c function in KVM for s390 in the Linux kernel. This flaw allows a local attacker with a normal user privilege to obtain unauthorized memory write access. This flaw affects Linux kernel versions prior to 5.17-rc4.
(CVE-2022-0516)

- A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

- kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
