high Tenable Cloud Security Plugin ID 475322

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: erofs: skip sufficiently large global
 buffers when resizing z_erofs_gbuf_nrpages is advanced only after every global buffer has been grown. If a
 resize fails after some buffers were enlarged, a retry revisits those enlarged buffers. Retrying the same
 size then returns -ENOMEM because alloc_pages_bulk() has no pages to add and the unchanged return value is
 treated as a failure. Retrying an intermediate size allocates a temporary pointer array smaller than
 gbuf->nrpages and copies more existing pointers than the array can hold. Skip buffers that already satisfy
 the request. Once all remaining buffers have caught up, advancing z_erofs_gbuf_nrpages again describes the
 guaranteed minimum size across the pool. (CVE-2026-89602)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
