For SDP VFs this leads to\ninvalid memory access as it was not initialized.\n\nThis patch adds a NULL check for `queue_to_pfc_map` before\ndereferencing it. Also, simplifies the logic by always assigning a\ndefault BPID first, then conditionally overriding it if CONFIG_DCB is\nenabled and the map exists."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/marvell/octeontx2/nic/cn20k.c","drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.c","drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.h"],"versions":[{"version":"184fb40f731bd3353b0887731f7caba66609e9cd","lessThan":"59fbbded05e559675930fd521b8d62b72828b52d","status":"affected","versionType":"git"},{"version":"184fb40f731bd3353b0887731f7caba66609e9cd","lessThan":"056994563935e049093f100efaad7e63ad113814","status":"affected","versionType":"git"},{"version":"22079d5ae4a33679150f7de89f4107f4e0446886","status":"affected","versionType":"git"},{"version":"6.14.9","lessThan":"6.15","status":"affected","versionType":"semver"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/marvell/octeontx2/nic/cn20k.c","drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.c","drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.h"],"versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.2.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.14.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/59fbbded05e559675930fd521b8d62b72828b52d"},{"url":"https://git.kernel.org/stable/c/056994563935e049093f100efaad7e63ad113814"}],"title":"octeontx2-pf: Fix aura BPID assignment when CONFIG_DCB is enabled","x_generator":{"engine":"bippy-1.2.0"}}}}
