Unity Linux 20.1070e Security Update: kernel (UTSA-2025-990896)

high Nessus Plugin ID 275005

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-2025-990896 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 jfs: Fix uninit-value access of new_ea in ea_buffer

 syzbot reports that lzo1x_1_do_compress is using uninit-value:

 ===================================================== BUG: KMSAN: uninit-value in lzo1x_1_do_compress+0x19f9/0x2510 lib/lzo/lzo1x_compress.c:178

 ...

 Uninit was stored to memory at:
 ea_put fs/jfs/xattr.c:639 [inline]

 ...

 Local variable ea_buf created at:
 __jfs_setxattr+0x5d/0x1ae0 fs/jfs/xattr.c:662
 __jfs_xattr_set+0xe6/0x1f0 fs/jfs/xattr.c:934

 =====================================================

 The reason is ea_buf->new_ea is not initialized properly.

 Fix this by using memset to empty its content at the beginning in ea_get().

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

Update the affected kernel package.
