Detailsinfo

A vulnerability has been found in Linux Kernel up to 5.10.187/5.15.120/6.1.38/6.3.12/6.4.3 and classified as critical. This vulnerability affects the function bnxt_re. The manipulation with an unknown input leads to a initialization vulnerability. The CWE definition for the vulnerability is CWE-665. The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: wraparound mbox producer index Driver is not handling the wraparound of the mbox producer index correctly. Currently the wraparound happens once u32 max is reached. Bit 31 of the producer index register is special and should be set only once for the first command. Because the producer index overflow setting bit31 after a long time, FW goes to initialization sequence and this causes FW hang. Fix is to wraparound the mbox producer index once it reaches u16 max.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2023-53201 since 09/15/2025. There are known technical details, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 270831 (SUSE SLES12 Security Update : kernel (SUSE-SU-2025:03614-1)), which helps to determine the existence of the flaw in a target environment.
