Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the parse_dacl process. An attacker can cause excessive kernel memory allocations and potentially exhaust system resources by sending a crafted SMB2 security descriptor with an undersized DACL, which bypasses bounds validation and drives large heap allocations. This is only exploitable if the attacker has an authenticated SMB session with FILE_WRITE_DAC or FILE_WRITE_OWNER access on a writable share and can send malicious SMB2 protocol requests to an exposed ksmbd server.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
