Azure Linux 3.0 Security Update: hyperv-daemons (CVE-2024-27393)

medium Nessus Plugin ID 295709

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of hyperv-daemons installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-27393 advisory.

 - In the Linux kernel, the following vulnerability has been resolved: xen-netfront: Add missing skb_mark_for_recycle Notice that skb_mark_for_recycle() is introduced later than fixes tag in commit 6a5bcd84e886 (page_pool: Allow drivers to hint on SKB recycling). It is believed that fixes tag were missing a call to page_pool_release_page() between v5.9 to v5.14, after which is should have used skb_mark_for_recycle(). Since v6.6 the call page_pool_release_page() were removed (in commit 535b9c61bdef (net: page_pool: hide page_pool_release_page()) and remaining callers converted (in commit 6bfef2ec0172 (Merge branch 'net-page_pool-remove-page_pool_release_page')). This leak became visible in v6.8 via commit dba1b8a7ab68 (mm/page_pool: catch page_pool memory leaks). (CVE-2024-27393)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
