{"id":"CVE-2026-53380","summary":"media: rzv2h-ivc: Fix concurrent buffer list access","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: rzv2h-ivc: Fix concurrent buffer list access\n\nThe list of buffers (`rzv2h_ivc::buffers.queue`) is protected by a\nspinlock (`rzv2h_ivc::buffers.lock`). However, in\n`rzv2h_ivc_transfer_buffer()`, which runs in a separate workqueue, the\n`list_del()` call is executed without holding the spinlock, which makes\nit possible for the list to be concurrently modified\n\nFix that by removing a buffer from the list in the lock protected section.\n\n[assign ivc-\u003ebuffers.curr in critical section as reported by Barnabas]","modified":"2026-07-22T05:30:13.257001526Z","published":"2026-07-19T10:02:02.030Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53380.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/72773ff1cdfaebc593f53b1719b2c1773ecf8c43"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c746522bd3264132ab2e2382e96e19cdb8a6c1ba"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53380.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53380"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f0b3984d821b3a603cd8786dca6cc73d47c4521a"},{"fixed":"c746522bd3264132ab2e2382e96e19cdb8a6c1ba"},{"fixed":"72773ff1cdfaebc593f53b1719b2c1773ecf8c43"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53380.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53380.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
