Detailsinfo

A vulnerability was found in Linux Kernel up to 6.14.1. It has been classified as problematic. Affected is some unknown processing of the component bnxt_en. The impact remains unknown. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2025-22108 since 12/29/2024. The technical details are unknown and an exploit is not available.
