Unity Linux 20.1050e Security Update: kernel (UTSA-2026-006635)
medium Nessus Plugin ID 305564
Synopsis
The Unity Linux host is missing one or more security updates.Description
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-006635 advisory.In the Linux kernel, the following vulnerability has been resolved:
jfs: add check read-only before truncation in jfs_truncate_nolock()
Added a check for read-only mode in the `jfs_truncate_nolock` function to avoid errors related to writing to a read-only filesystem.
Call stack:
block_write_begin() { jfs_write_failed() { jfs_truncate() { jfs_truncate_nolock() { txEnd() { ...
log = JFS_SBI(tblk->sb)->log;
// (log == NULL)
If the `isReadOnly(ip)` condition is triggered in `jfs_truncate_nolock`, the function execution will stop, and no further data modification will occur. Instead, the `xtTruncate` function will be called with the COMMIT_WMAP flag, preventing modifications in read-only mode.
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
