- Summary
- CVE-2024-50135 affecting package kernel 5.15.200.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix race condition between reset and nvmedevdisable()
nvmedevdisable() modifies the dev->onlinequeues field, therefore nvmepciupdatenrqueues() should avoid racing against it, otherwise we could end up passing invalid values to blkmqupdatenrhwqueues().
WARNING: CPU: 39 PID: 61303 at drivers/pci/msi/api.c:347 pciirqgetaffinity+0x187/0x210 Workqueue: nvme-reset-wq nvmeresetwork [nvme] RIP: 0010:pciirqgetaffinity+0x187/0x210 Call Trace: <TASK> ? blkmqpcimapqueues+0x87/0x3c0 ? pciirqgetaffinity+0x187/0x210 blkmqpcimapqueues+0x87/0x3c0 nvmepcimapqueues+0x189/0x460 [nvme] blkmqupdatenrhwqueues+0x2a/0x40 nvmereset_work+0x1be/0x2a0 [nvme]
Fix the bug by locking the shutdownlock mutex before using dev->onlinequeues. Give up if nvmedevdisable() is running or if it has been executed already.
