high Tenable Self-Hosted Container Security Plugin ID 468801

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: RDMA/mlx5: Fix stack out-of-bounds
read in cc_params debugfs get_param() reads a congestion parameter as a u32 but formats it with the signed
"%d" into an 11-byte stack buffer. A value with bit 31 set, such as 0x80000000, renders as "-2147483648\n"
whose full length is 12. snprintf() stores only 11 bytes yet returns 12, so simple_read_from_buffer()
treats 12 bytes as valid and reads one byte past lbuf[]. Size the buffer for the widest unsigned decimal,
format with "%u" to match the u32, and use scnprintf() so the length passed to simple_read_from_buffer()
reflects the bytes actually stored. (CVE-2026-90416)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
