However, because\nbuffer.data was left uninitialized (NULL), qede_reuse_page() pushes a\n\"ghost\" BD (valid DMA mapping but NULL data pointer) back into the\nactive Rx ring.\n\nThe next time the hardware uses this ring slot, it passes a NULL page\nto qede_fill_frag_skb(), causing a kernel panic.\n\nExample crash from production system:\n BUG: unable to handle kernel NULL pointer dereference at 0x8\n RIP: qede_fill_frag_skb+0x96/0x430 [qede]\n Call Trace:\n qede_rx_int+0xb06/0x1de0\n qede_poll+0x2f4/0x6c0\n __napi_poll+0x2d/0x130\n\nFix the root cause by restoring the tpa_info->buffer.data assignment\nin qede_tpa_start(), ensuring valid pages are correctly tracked and\nrecycled. Additionally, update the stale comment for\nstruct qede_agg_info::buffer to reflect its current usage.","state":0,"publishedAt":"2026-09-11T19:43:56.64+00:00","modifiedAt":"2026-10-19T08:48:02.658+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/qlogic/qede/qede.h\",\n \"drivers/net/ethernet/qlogic/qede/qede_fp.c\"\n ],\n \"versions\": [\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"e2214e2793154b745436e46c6a9a7985d9b3781d\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"dd8bc0a9d87d2b048711edd17ba7286432edd285\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"fa7c9bd2c4a8de167e2fb32968ca4d91dd774375\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"a5e1fdc126ab337d601d1a00cc4b47910679d005\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"7f911e208b3ca2c76d9f2bbba1f54b9403568c10\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"2a952fb1b20d83e83ca852773e6188511f7d2191\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"f5c8619ccbd70102642120c4c6fda1c048a555fd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8a8633978b842c88fbcfe00d4e5dde96048f630e\",\n \"lessThan\": \"06aa3d26327f24edd039ff249672fdf6f2ba5695\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/qlogic/qede/qede.h\",\n \"drivers/net/ethernet/qlogic/qede/qede_fp.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.18\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.18\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.270\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.221\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.188\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.157\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.109\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.50\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2.4\",\n \"lessThanOrEqual\": \"7.2.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.3\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/e2214e2793154b745436e46c6a9a7985d9b3781d","https://git.kernel.org/stable/c/dd8bc0a9d87d2b048711edd17ba7286432edd285","https://git.kernel.org/stable/c/fa7c9bd2c4a8de167e2fb32968ca4d91dd774375","https://git.kernel.org/stable/c/a5e1fdc126ab337d601d1a00cc4b47910679d005","https://git.kernel.org/stable/c/7f911e208b3ca2c76d9f2bbba1f54b9403568c10","https://git.kernel.org/stable/c/2a952fb1b20d83e83ca852773e6188511f7d2191","https://git.kernel.org/stable/c/f5c8619ccbd70102642120c4c6fda1c048a555fd","https://git.kernel.org/stable/c/06aa3d26327f24edd039ff249672fdf6f2ba5695"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89511","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89511","identifiers":["CVE-2026-89511"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
