UBUNTU-CVE-2025-22057: Medium severity ubuntu/linux-azure vulnerability

Q: Which Ubuntu systems are most likely to be exposed?

Exposure is indicated for the listed Ubuntu Linux kernel packages, including linux, linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, linux-azure, linux-gcp, and linux-oracle, when CONFIG_DST_CACHE is enabled and Open vSwitch with tunnels is used.

Q: What level of access does an attacker need?

The severity vector indicates local access and low privileges are required. No user interaction is required.

Q: What is the practical impact if the issue is triggered?

The reported failure is a kernel paging request during destination-cache cleanup, and the vector rates availability impact as high. The supplied data does not indicate confidentiality or integrity impact.

Updated

In the Linux kernel, the following vulnerability has been resolved: net: decrease cached dst counters in dstrelease Upstream fix ac888d58869b ("net: do not delay dstentriesadd() in dstrelease()") moved decrementing the dst count from dstdestroy to dstrelease to avoid accessing already freed data in case of netns dismantle. However in case CONFIGDSTCACHE is enabled and OvS+tunnels are used, this fix is incomplete as the same issue will be seen for cached dsts: Unable to handle kernel paging request at virtual address ffff5aabf6b5c000 Call trace: percpucounteraddbatch+0x3c/0x160 (P) dstrelease+0xec/0x108 dstcachedestroy+0x68/0xd8 dstdestroy+0x13c/0x168 dstdestroyrcu+0x1c/0xb0 rcudobatch+0x18c/0x7d0 rcucore+0x174/0x378 rcucoresi+0x18/0x30 Fix this by invalidating the cache, and thus decrementing cached dst counters, in dstrelease too.

Frequently Asked Questions

Which Ubuntu systems are most likely to be exposed?

Exposure is indicated for the listed Ubuntu Linux kernel packages, including linux, linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, linux-azure, linux-gcp, and linux-oracle, when CONFIG_DST_CACHE is enabled and Open vSwitch with tunnels is used.

What level of access does an attacker need?

The severity vector indicates local access and low privileges are required. No user interaction is required.

What is the practical impact if the issue is triggered?

The reported failure is a kernel paging request during destination-cache cleanup, and the vector rates availability impact as high. The supplied data does not indicate confidentiality or integrity impact.
