Detailsinfo

A vulnerability was found in Linux Kernel up to 6.0.8 and classified as problematic. This issue affects some unknown processing of the component octeontx2-pf. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: Fix SQE threshold checking Current way of checking available SQE count which is based on HW updated SQB count could result in driver submitting an SQE even before CQE for the previously transmitted SQE at the same index is processed in NAPI resulting losing SKB pointers, hence a leak. Fix this by checking a consumer index which is updated once CQE is processed.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2022-49858 since 05/01/2025. Neither technical details nor an exploit are publicly available.
