Bottlerocket: bottlerocket-kernel-6.12, kernel-6.12: security update to 6.12.29

medium Tenable Cloud Security Plugin ID 428258

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: bnxt_en: Mask the bd_cnt field in the
TX BD properly The bd_cnt field in the TX BD specifies the total number of BDs for the TX packet. The
bd_cnt field has 5 bits and the maximum number supported is 32 with the value 0. CONFIG_MAX_SKB_FRAGS can
be modified and the total number of SKB fragments can approach or exceed the maximum supported by the
chip. Add a macro to properly mask the bd_cnt field so that the value 32 will be properly masked and set
to 0 in the bd_cnd field. Without this patch, the out-of-range bd_cnt value will corrupt the TX BD and may
cause TX timeout. The next patch will check for values exceeding 32. (CVE-2025-22108)

Solution

Update the bottlerocket-kernel-6.12 library and its related packages to version 6.12.29 or later.
