CVE-2025-22080 fs/ntfs3: Prevent integer overflow in hdr_first_de()

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Prevent integer overflow in hdrfirstde The "deoff" and "used" variables come from the disk so they both need to check. The problem is that on 32bit systems if they're both greater than UINTMAX - 16 then the check does...

CVE-2025-22074 ksmbd: fix r_count dec/increment mismatch

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix rcount dec/increment mismatch rcount is only increased when there is an oplock break wait, so rcount inc/decrement are not paired. This can cause rcount to become negative, which can lead to a problem where the ksmbd...

CVE-2025-22074

The CVE-2025-22074 issue concerns the ksmbd component in the Linux kernel where r_count increments are not paired with decrements except when an oplock break wait occurs. This can make r_count go negative, which may prevent the ksmbd thread from terminating. Technical detail confirmed in connecte...
