Vulnerability from github – Published: 2024-05-21 15:31 – Updated: 2024-12-26 18:30

Details

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

net: macb: fix use after free on rmmod

plat_dev->dev->platform_data is released by platform_device_unregister(), use of pclk and hclk is a use-after-free. Since device unregister won't need a clk device we adjust the function call sequence to fix this issue.

[ 31.261225] BUG: KASAN: use-after-free in macb_remove+0x77/0xc6 [macb_pci] [ 31.275563] Freed by task 306: [ 30.276782] platform_device_release+0x25/0x80

Severity ?

7.8 (High)
