Details

In the Linux kernel, the following vulnerability has been resolved:

pdscore: remove write-after-free of clientid

A use-after-free error popped up in stress testing:

[Mon Apr 21 21:21:33 2025] BUG: KFENCE: use-after-free write in pdscauxbusdevdel+0xef/0x160 [pdscore] [Mon Apr 21 21:21:33 2025] Use-after-free write at 0x000000007013ecd1 (in kfence-#47): [Mon Apr 21 21:21:33 2025] pdscauxbusdevdel+0xef/0x160 [pdscore] [Mon Apr 21 21:21:33 2025] pdscremove+0xc0/0x1b0 [pdscore] [Mon Apr 21 21:21:33 2025] pcideviceremove+0x24/0x70 [Mon Apr 21 21:21:33 2025] devicereleasedriverinternal+0x11f/0x180 [Mon Apr 21 21:21:33 2025] driverdetach+0x45/0x80 [Mon Apr 21 21:21:33 2025] busremovedriver+0x83/0xe0 [Mon Apr 21 21:21:33 2025] pciunregisterdriver+0x1a/0x80

The actual device uninit usually happens on a separate thread scheduled after this code runs, but there is no guarantee of order of thread execution, so this could be a problem. There's no actual need to clear the client_id at this point, so simply remove the offending code.
