But there is a chance of all allocated MCAM entries not being freed by PF/VF. Hence free mcam entries even in case of detached LF. The Linux kernel CVE team has assigned CVE-2022-50060 to this issue. Affected and fixed versions =========================== Issue introduced in 5.0 with commit c554f9c1574e022821260b24b043a4277e8ec5d8 and fixed in 5.15.63 with commit dc5be2d4f9285efe0d16f1bf00250df91d05d809 Issue introduced in 5.0 with commit c554f9c1574e022821260b24b043a4277e8ec5d8 and fixed in 5.19.4 with commit cc32347f48111eea8d0165538c92aca92ede83f6 Issue introduced in 5.0 with commit c554f9c1574e022821260b24b043a4277e8ec5d8 and fixed in 6.0 with commit 3f8fe40ab7730cf8eb6f8b8ff412012f7f6f8f48 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community.

The official CVE entry at https://cve.org/CVERecord/?id=CVE-2022-50060 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/marvell/octeontx2/af/rvu.c drivers/net/ethernet/marvell/octeontx2/af/rvu_npc.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/dc5be2d4f9285efe0d16f1bf00250df91d05d809 https://git.kernel.org/stable/c/cc32347f48111eea8d0165538c92aca92ede83f6 https://git.kernel.org/stable/c/3f8fe40ab7730cf8eb6f8b8ff412012f7f6f8f48
