In the Linux kernel, the following vulnerability has been resolved:

fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath

When cifs_sanitize_prepath is called with an empty string or a string
containing only delimiters (e.g., "/"), the current logic attempts to
check *(cursor2 - 1) before cursor2 has advanced. This results in an
out-of-bounds read.

This patch adds an early exit check after stripping prepended
delimiters. If no path content remains, the function returns NULL.

The bug was identified via manual audit and verified using a
standalone test case compiled with AddressSanitizer, which
triggered a SEGV on affected inputs.

In the Linux kernel, the following vulnerability has been resolved: fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath When cifs_sanitize_prepath is called with an empty string or a string containing only delimiters (e.g., "/"), the current logic attempts to check *(cursor2 - 1) before cursor2 has advanced.

The bug was identified via manual audit and verified using a standalone test case compiled with AddressSanitizer, which triggered a SEGV on affected inputs.

CVE-2026-43112 is a high-severity vulnerability in the Linux kernel's CIFS client, specifically in the cifs_sanitize_prepath function. The flaw causes an out-of-bounds read when processing empty or delimiter-only strings, potentially leading to a system crash and denial of service. The issue affects certain Linux kernel versions and has been fixed in later releases. Mitigation includes applying the official patches or disabling the CIFS kernel module if CIFS functionality is not required.
