Google: sys-kernel/csql-kernel-6_1, sys-kernel/tpusev-kernel-6_6: security update to 18613.613.5

critical Tenable Cloud Security Plugin ID 467086

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: net/ipv6: ioam6: prevent schema length
wraparound in trace fill ioam6_fill_trace_data() stores the schema contribution to the trace length in a
u8. With bit 22 enabled and the largest schema payload, sclen becomes 1 + 1020 / 4, wraps from 256 to 0,
and bypasses the remaining-space check. __ioam6_fill_trace_data() then positions the write cursor without
reserving the schema area but still copies the 4-byte schema header and the full schema payload,
overrunning the trace buffer. Keep sclen in an unsigned int so the remaining-space check and the write
cursor calculation both see the full schema length. (CVE-2026-43341)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.5 or later.
