Vulnerability Details : CVE-2022-48754
In the Linux kernel, the following vulnerability has been resolved:
phylib: fix potential use-after-free
Commit bafbdd527d56 ("phylib: Add device reset GPIO support") added call
to phy_device_reset(phydev) after the put_device() call in phy_detach().
The comment before the put_device() call says that the phydev might go
away with put_device().
Fix potential use-after-free by calling phy_device_reset() before
put_device().

CWE ids for CVE-2022-48754
-
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.Assigned by: 134c704f-9b21-4f2e-91b3-4a467353bcc0 (Secondary)
