{"apiVersion":"1.0","identifier":"CVE-2026-74542","description":"In the Linux kernel, the following vulnerability has been resolved: netfs: Fix folio_queue ENOMEM in writeback by adding a mempool Fix the handling of folio_queue allocation failure in writeback by adding a mempool and passing in gfp_t flags to the rolling buffer functions that allocate memory, using the mempool if gfp != GFP_KERNEL. This is then extended upwards and the gfp to be used for a request is stored in the netfs_io_request struct and is then used for both requests and subrequests, eliminating the sleeping loops there. The failure caused: folio != NULL WARNING: fs/netfs/write_issue.c:603 at netfs_writepages+0x883/0xa10 fs/netfs/write_issue.c:603, CPU#3: syz.0.17/5919","publishedAt":"2026-08-15T13:17:59","lastModifiedAt":"2026-08-17T06:19:51","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74542","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00155,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74542","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74542","en":"https://www.redsauce.net/en/cves/CVE-2026-74542","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74542","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74542","de":"https://www.redsauce.net/de/cves/CVE-2026-74542","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74542","el":"https://www.redsauce.net/el/cves/CVE-2026-74542"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74542"}}
