{"id":"AZL-103044","summary":"CVE-2026-90416 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Fix stack out-of-bounds read in cc_params debugfs\n\nget_param() reads a congestion parameter as a u32 but formats it with the\nsigned \"%d\" into an 11-byte stack buffer. A value with bit 31 set, such as\n0x80000000, renders as \"-2147483648\\n\" whose full length is 12. snprintf()\nstores only 11 bytes yet returns 12, so simple_read_from_buffer() treats 12\nbytes as valid and reads one byte past lbuf[].\n\nSize the buffer for the widest unsigned decimal, format with \"%u\" to match\nthe u32, and use scnprintf() so the length passed to\nsimple_read_from_buffer() reflects the bytes actually stored.","modified":"2026-09-18T14:18:02.994143278Z","published":"2026-09-17T17:17:45Z","upstream":["CVE-2026-90416"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90416"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103044.json"}}],"schema_version":"1.9.0"}
