CVE-2026-89632

CVE-2026-89632 is an out-of-bounds read in the Linux kernel's SMB client , specifically in the reparse_buf_ptr() function. The root cause is a use-before-check of ReparseDataLength (offset 4, 2 bytes): the value is read before verifying that the received buffer length (count) is at least the full...

PT-2026-90348

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the SMB client where the reparse buf ptr function reads the ReparseDataLength variable before verifying that the count covers the full fixed header. If a server return...

CVE-2024-49996

In the Linux kernel, the following vulnerability has been resolved: cifs: Fix buffer overflow when parsing NFS reparse points ReparseDataLength is sum of the InodeType size and DataBuffer size. So to get DataBuffer size it is needed to subtract InodeType's size from ReparseDataLength. Function...

CVE-2024-49996

CVE-2024-49996 affects the Linux kernel CIFS/SMB client when parsing NFS reparse points. The root cause is a buffer length miscalculation in cifs_strndup_from_utf16() that doesn’t subtract InodeType size from ReparseDataLength, allowing reads past the buffer. The InodeType field and Major/Minor R...
