- Summary
- CVE-2024-38780 affecting package kernel for versions less than 5.15.162.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
dma-buf/sw-sync: don't enable IRQ from syncprintobj()
Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from known context") by error replaced spinunlockirqrestore() with spinunlockirq() for both syncdebugfsshow() and syncprintobj() despite syncprintobj() is called from syncdebugfsshow(), lockdep complains inconsistent lock state warning.
Use plain spin_{lock,unlock}() for syncprintobj(), for syncdebugfsshow() is already using spin_{lock,unlock}_irq().
