CVE-2024-0565: Kernel: cifs filesystem decryption improper input validation remote code execution vulnerability in function receive_encrypted_standard of client
Noroxi assessment
Priority: Monitor (action score 30/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.9% (FIRST EPSS); higher than 80.6% of all records.
- Someone on the same network segment can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: Linux kernel 5.10.211, 5.15.150, 6.1.69.
Low priority for now. Upgrade to Linux kernel 5.10.211, 5.15.150, 6.1.69 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service.
