{"apiVersion":"1.0","identifier":"CVE-2026-74403","description":"In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Check for page allocation failure correctly in TIO Sashiko notes: > if __snp_alloc_firmware_pages() returns NULL under memory pressure, is it > safe to pass it directly to page_address()? > > On architectures without HASHED_PAGE_VIRTUAL, page_address(NULL) might > compute a deterministic but invalid, non-zero virtual address. The > subsequent if (tio_status) check would then evaluate to true, and > sev_tsm_init_locked() would dereference the invalid pointer. Indeed, page_address(NULL) will return non-NULL garbage here. Fix this by checking the page allocation itself for NULL, not the resulting virtual address.","publishedAt":"2026-08-15T06:22:42","lastModifiedAt":"2026-08-17T06:19:35","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74403","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00121,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74403","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74403","en":"https://www.redsauce.net/en/cves/CVE-2026-74403","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74403","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74403","de":"https://www.redsauce.net/de/cves/CVE-2026-74403","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74403","el":"https://www.redsauce.net/el/cves/CVE-2026-74403"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74403"}}
