GHSA-7PRJ-H6R4-GH9J
Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2025-01-14 18:31In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix racing issue between ufshcd_mcq_abort() and ISR
If command timeout happens and cq complete IRQ is raised at the same time, ufshcd_mcq_abort clears lprb->cmd and a NULL pointer deref happens in the ISR. Error log:
ufshcd_abort: Device abort task at tag 18 Unable to handle kernel NULL pointer dereference at virtual address 0000000000000108 pc : [0xffffffe27ef867ac] scsi_dma_unmap+0xc/0x44 lr : [0xffffffe27f1b898c] ufshcd_release_scsi_cmd+0x24/0x114
