CVE-2024-27418: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: net: mctp: take ownership of skb in mctp_local_output Currently, mctp_local_output only takes ownership of skb on success, and we may leak an skb if mctp_local_output fails in specific states; the skb ownership isn't transferred until the actual output routing occurs. Instead, make mctp_local_output free the skb on all error paths up to the route action, so it always consumes the passed skb.

Affected products

• Linux Linux Kernel: from 5.15, before 6.1.81 (fixed in 6.1.81); from 6.2, before 6.6.21 (fixed in 6.6.21); from 6.7, before 6.7.9 (fixed in 6.7.9); version 6.8 only
