high Tenable Self-Hosted Container Security Plugin ID 470234

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: ipvs: avoid out-of-bounds write in
ip_vs_nat_icmp Sashiko warns that local attacker can modify the packet while it is processed by IPVS. Some
places read the IP ihl field multiple times which can cause out-of-bounds access. One such place is
ip_vs_nat_icmp where we can write after the validated area. Fix it by providing ciph argument just like it
is done for IPv6 and use ciph->len as offset to the embedded transport header. Modify some IPv4 header
checks by reading the ihl field only once. (CVE-2026-74724)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.28 or later.
