UBUNTU-CVE-2026-98113

In the Linux kernel, the following vulnerability has been resolved: ksmbd: rate limit unmapped SID errors A client can include many structurally valid but unmapped SIDs in a DACL. Logging every mapping failure lets one request generate hundreds of kernel error messages. Rate limit the message to...

CVE-2026-98127 smb/client: validate new EOF for insert range

In the Linux kernel, the following vulnerability has been resolved: smb/client: validate new EOF for insert range smb3insertrange does not check if the new file size isize + len is valid. This allows FALLOCFLINSERTRANGE to bypass RLIMITFSIZE, exceed smaxbytes, or produce a size outside the lofft...

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...

CVE-2026-98125 smb/client: fix stale page cache in insert/collapse range

In the Linux kernel, the following vulnerability has been resolved: smb/client: fix stale page cache in insert/collapse range smb3insertrange and smb3collapserange use truncatepagecacherange to invalidate the affected page cache. However, if off or oldeof is not page-aligned, the boundary pages a...

CVE-2026-98125

The Linux kernel contains a vulnerability in the smb/client component where smb3_insert_range() and smb3_collapse_range() may return stale data . The issue occurs because truncate_pagecache_range() only partially zeroes boundary pages when the offset or old EOF is not page-aligned , leaving them ...

CVE-2026-98126

A vulnerability in the Linux kernel smb/client allows a file to grow beyond the caller's file-size limit. When FALLOC_FL_ZERO_RANGE is used without FALLOC_FL_KEEP_SIZE , the smb3_zero_range() function may extend the EOF without checking RLIMIT_FSIZE . The issue is resolved by calling inode_newsiz...

CVE-2026-98126 smb/client: validate new EOF for zero range

In the Linux kernel, the following vulnerability has been resolved: smb/client: validate new EOF for zero range When FALLOCFLZERORANGE is used without FALLOCFLKEEPSIZE, smb3zerorange may extend EOF without checking RLIMITFSIZE, allowing the file to grow beyond the caller's file-size limit. Fix th...

CVE-2026-98124

The Linux kernel contains a vulnerability in the smb/client component where specific server-side range operations—smb3_zero_range() , smb3_punch_hole() , smb3_insert_range() , and smb3_collapse_range() —fail to properly invalidate the FS-Cache . While these operations discard the affected page ca...
