CVSS 8.2 · High EPSS 0,44%
Kerentanan pada linux kernel. Skor CVSS 3.1 8.2 (High) menurut CNA.
In the Linux kernel, the following vulnerability has been resolved: smb: client: harden POSIX SID length parsing posix_info_sid_size() reads sid[1] to obtain the subauthority count, but its existing boundary check still accepts buffers with only one remaining byte. Require two bytes before reading sid[1] so all client paths that reuse the helper reject truncated POSIX SIDs safely.
