{"apiVersion":"1.0","identifier":"CVE-2026-74319","description":"In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: fix deadlock waiting for ticket during data relocation When performing data relocation on a zoned filesystem, BTRFS can deadlock in handle_reserve_tickets(). The relocation process is waiting on a space reservation ticket that can never be fulfilled, because the relocation itself is the operation responsible for freeing up that space. Fix this by introducing a new flush state, BTRFS_RESERVE_FLUSH_ZONED_RELOCATION, specifically for data chunk allocation during zoned relocation. Like BTRFS_RESERVE_FLUSH_FREE_SPACE_INODE, this state uses priority_reclaim_data_space() instead of the normal flushing path, which avoids re-entering the relocation code and breaking the deadlock cycle. In btrfs_alloc_data_chunk_ondemand(), select this new flush state when the inode belongs to a data relocation root on a zoned filesystem.","publishedAt":"2026-08-15T06:22:32","lastModifiedAt":"2026-08-17T06:19:26","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74319","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-2026-74319","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74319","en":"https://www.redsauce.net/en/cves/CVE-2026-74319","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74319","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74319","de":"https://www.redsauce.net/de/cves/CVE-2026-74319","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74319","el":"https://www.redsauce.net/el/cves/CVE-2026-74319"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74319"}}
