This bitmap is indexed by queue number\nand is set by ice_offload_txtime(), which only operates on PF VSI\nqueues.\n\nHowever, ice_is_txtime_ena() does not check the VSI type before\nconsulting the bitmap. When ETF offload is enabled on PF Tx queue 0,\nbit 0 is set in pf->txtime_txqs. During a subsequent PCI reset\nrebuild, the CTRL VSI's Tx queue 0 is reconfigured and\nice_is_txtime_ena() is called for that ring. Since it only checks\npf->txtime_txqs by queue index without distinguishing VSI type, it\nfinds bit 0 set and returns true, matching the PF VSI's ETF queue,\nnot the CTRL VSI's. This causes ice_vsi_cfg_txq() to spuriously\nallocate a tstamp_ring for the CTRL VSI ring.\n\nSince CTRL VSI rings have no associated netdev, ice_clean_tx_ring()\ntakes an early return at the !netdev check before reaching\nice_free_tx_tstamp_ring(), leaking the allocation. Each PCI reset\nleaks one 64-byte tstamp_ring.\n\nFix this by restricting ice_is_txtime_ena() to return true only for\nPF VSI rings, since txtime_txqs is only meaningful for PF VSI queues."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/ice/ice.h"],"versions":[{"version":"ccde82e909467abdf098a8ee6f63e1ecf9a47ce5","lessThan":"684d4d0bda95a3fb21b3e29ff0f668f657707b54","status":"affected","versionType":"git"},{"version":"ccde82e909467abdf098a8ee6f63e1ecf9a47ce5","lessThan":"d0a21604c6abfa4956f3a511a1de174cec77a812","status":"affected","versionType":"git"},{"version":"ccde82e909467abdf098a8ee6f63e1ecf9a47ce5","lessThan":"144539bbfd3cea1ab0fb6f5216d6004c1f4f029b","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/ice/ice.h"],"versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.18.42","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.6","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"6.18","versionEndExcluding":"6.18.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/684d4d0bda95a3fb21b3e29ff0f668f657707b54"},{"url":"https://git.kernel.org/stable/c/d0a21604c6abfa4956f3a511a1de174cec77a812"},{"url":"https://git.kernel.org/stable/c/144539bbfd3cea1ab0fb6f5216d6004c1f4f029b"}],"title":"ice: prevent tstamp ring allocation for non-PF VSI types","x_generator":{"engine":"bippy-1.2.0"}}}}
