Unity Linux 20.1050e Security Update: kernel (UTSA-2026-007364)

medium Nessus Plugin ID 307271

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-2026-007364 advisory.

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

scsi: qla2xxx: Fix memory leak in qla2x00_probe_one()

There is a memory leak reported by kmemleak:

unreferenced object 0xffffc900003f0000 (size 12288):
comm modprobe, pid 19117, jiffies 4299751452 (age 42490.264s) hex dump (first 32 bytes):
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

backtrace:
[<00000000629261a8>] __vmalloc_node_range+0xe56/0x1110 [<0000000001906886>] __vmalloc_node+0xbd/0x150 [<000000005bb4dc34>] vmalloc+0x25/0x30 [<00000000a2dc1194>] qla2x00_create_host+0x7a0/0xe30 [qla2xxx] [<0000000062b14b47>] qla2x00_probe_one+0x2eb8/0xd160 [qla2xxx] [<00000000641ccc04>] local_pci_probe+0xeb/0x1a0

The root cause is traced to an error-handling path in qla2x00_probe_one() when the adapter base_vha initialize failed. The fab_scan_rp scan.l is used to record the port information and it is allocated in qla2x00_create_host(). However, it is not released in the error handling path probe_failed.

Fix this by freeing the memory of scan.l when an error occurs in the adapter initialization process.

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.
