发布于3月6日3月6日 Members Debian: CVE-2024-38780: linux -- security update Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:N/A:C) Published 06/21/2024 Created 06/28/2024 Added 06/27/2024 Modified 01/30/2025 Description In the Linux kernel, the following vulnerability has been resolved: dma-buf/sw-sync: don't enable IRQ from sync_print_obj() Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from known context") by error replaced spin_unlock_irqrestore() with spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite sync_print_obj() is called from sync_debugfs_show(), lockdep complains inconsistent lock state warning. Use plain spin_{lock,unlock}() for sync_print_obj(), for sync_debugfs_show() is already using spin_{lock,unlock}_irq().
