Rocky Linux 10.2 [CIQ] Security Update: virtio-win (crlba-2026_43594)

high Nessus Plugin ID 376426

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 10.2 host has a package installed that is affected by a vulnerability as referenced in the CIQ crlba-2026_43594 advisory.

 The virtio-win package provides paravirtualized network drivers for most Microsoft Windows operating systems. Paravirtualized drivers are virtualization-aware drivers used by fully virtualized guests running on Rocky Linux. Fully virtualized guests using the paravirtualized drivers gain significantly better I/O performance than fully virtualized guests running without the drivers.

 Bug Fix(es) and Enhancement(s):

 * [virtio-win][viogpu] Reject resolutions exceeding framebuffer segment capacity [rhel-10.2.z] (JIRA:Rocky Linux-192315)

 * Someone driver works with debug level >= 6 (debug message flood) [rhel-10.2.z] (JIRA:Rocky Linux-192589)

 * Virtio-win may not configure guest cache mode when using virtio-blk [rhel-10.2.z] (JIRA:Rocky Linux-192590)

 * viosock: Validate fd_count in VIOSockSelect against overflow and empt? [rhel-10.2.z] (JIRA:Rocky Linux-192592)

 * [Windows]Can not connect to VM via vsock after migration [rhel-10.2.z] (JIRA:Rocky Linux-192594)

 * [virtio-win][viogpu] Provide a way to set a custom screen resolution [rhel-10.2.z] (JIRA:Rocky Linux-192595)

 * [viogpudo] VM crashes with BSOD/black screen when setting invalid resolution values [rhel-10.2.z] (JIRA:Rocky Linux-192596)

 * netkvm: treat temporary TX queue full as retry, not drop [rhel-10.2.z] (JIRA:Rocky Linux-192610)

 * viosock: Fix spec compliance issues in WSP library and socket driver [rhel-10.2.z] (JIRA:Rocky Linux-192611)
