medium Tenable Self-Hosted Container Security Plugin ID 467352

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: netfilter: x_tables: avoid leaking
 percpu counter pointers The native and compat get-entries paths copy the fixed rule entry header from the
 kernelized rule blob to userspace before overwriting the entry's counter fields with a sanitized counter
 snapshot. On SMP kernels, entry->counters.pcnt contains the percpu allocation address used by x_tables
 rule counters. A caller can provide a userspace buffer that faults during the initial fixed-header copy
 after pcnt has been copied but before the later sanitized counter copy runs. The syscall then returns
 -EFAULT while leaving the raw percpu pointer in userspace. Copy only the fixed entry prefix before
 counters from the kernelized rule blob, then copy the sanitized counter snapshot into the counter field.
 Apply this ordering to the IPv4, IPv6, and ARP native and compat get-entries implementations so a fault
 cannot expose the internal percpu counter pointer. (CVE-2026-53219)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.3 or later.
