{"apiVersion":"1.0","identifier":"CVE-2026-74487","description":"In the Linux kernel, the following vulnerability has been resolved: binfmt_misc: restore write access when removing an entry Registering an entry with the MISC_FMT_OPEN_FILE flag opens the interpreter via open_exec() which denies write access to it for as long as the entry exists. Removing the entry closes the interpreter file via filp_close() but never restores write access, leaving the inode-s i_writecount permanently negative. Opening the interpreter for writing keeps failing with ETXTBSY long after the entry is gone until the inode is evicted from the inode cache. Commit 90f601b497d7 (-binfmt_misc: restore write access before closing files opened by open_exec()-) fixed the same imbalance in the error path of bm_register_write() but the actual removal path has been leaking the write denial since the introduction of the flag. Restore write access in put_binfmt_handler() before closing the interpreter file.","publishedAt":"2026-08-15T13:17:53","lastModifiedAt":"2026-08-23T13:16:44","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74487","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00177,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74487","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74487","en":"https://www.redsauce.net/en/cves/CVE-2026-74487","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74487","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74487","de":"https://www.redsauce.net/de/cves/CVE-2026-74487","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74487","el":"https://www.redsauce.net/el/cves/CVE-2026-74487"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74487"}}
