Answer in brief
CVE-2023-52755 records a Critical severity (CVSS 9.8) vulnerability in ksmbd: fix slab out of bounds write in smb_inherit_dacl(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic), linux/linux_kernel (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 9.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix slab out of bounds write in smb_inherit_dacl() slab out-of-bounds write is caused by that offsets is bigger than pntsd allocation size. This patch add the check to validate 3 offsets using allocation size.
