high Tenable Self-Hosted Container Security Plugin ID 474963

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: arm64: percpu: Fix LSE operations on
 {8,16}-bit types The assembly for __percpu_##name##_case_##sz() and __percpu_##name##_return_case_##sz()
 doesn't use the 'sfx' macro argument to form the LSE instruction. Without 'sfx', a W register argument
 will imply a 32-bit memory location, and consequently {8,16}-bit ops will erroneously read and write 32
 bits of memory when the LSE instruction is used. Fix this by appending 'sfx' to 'op_lse' to LSE
 instruction. It is not necessary (and not valid) to append 'sfx' to 'op_llsc', as 'op_llsc' is a register-
 register operation which does not access memory (and does not take a size suffix). (CVE-2026-98248)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
