EUVDB-ID: #VU79673
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-2163
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in BPF verifier caused by improper marking of
registers for precision tracking in certain situations. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel to the latest version.

The vulnerability exists due to improper access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses. A local user can gain arbitrary write access to kernel memory and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel to the latest version.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
EUVDB-ID: #VU82658
Risk: Low
CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2023-5178
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local authenticated user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the drivers/nvme/target/tcp.c in nvmet_tcp_free_crypto due to a logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. A local authenticated user can trigger a use-after-free error and escalate privileges on the system.
MitigationUpdate the affected package the Linux Kernel to the latest version.
