Google: sys-kernel/csql-kernel-6_6: security update to 18867.199.65

medium Tenable Cloud Security Plugin ID 467167

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: pNFS: Fix uninited ptr deref in
 block/scsi layout The error occurs on the third attempt to encode extents. When function
 ext_tree_prepare_commit() reallocates a larger buffer to retry encoding extents, the "layoutupdate_pages"
 page array is initialized only after the retry loop. But ext_tree_free_commitdata() is called on every
 iteration and tries to put pages in the array, thus dereferencing uninitialized pointers. An additional
 problem is that there is no limit on the maximum possible buffer_size. When there are too many extents,
 the client may create a layoutcommit that is larger than the maximum possible RPC size accepted by the
 server. During testing, we observed two typical scenarios. First, one memory page for extents is enough
 when we work with small files, append data to the end of the file, or preallocate extents before writing.
 But when we fill a new large file without preallocating, the number of extents can be huge, and counting
 the number of written extents in ext_tree_encode_commit() does not help much. Since this number increases
 even more between unlocking and locking of ext_tree, the reallocated buffer may not be large enough again
 and again. (CVE-2025-38691)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.199.65 or later.
