CVE-2026-98127

A vulnerability in the Linux kernel smb/client allows the smb3_insert_range() function to bypass size limits because it fails to validate the new file size. Specifically, it does not check if i_size + len is valid, enabling FALLOC_FL_INSERT_RANGE to bypass RLIMIT_FSIZE , exceed s_maxbytes , or re...
