A use-after-free flaw was found in lan78xx_disconnect in
drivers/net/usb/lan78xx.c in the network sub-component, net/usb/lan78xx in
the Linux Kernel. This flaw allows a local attacker to crash the system
when the LAN78XX USB device detaches.
Author | Note |
---|---|
Priority reason: Requires a device to be disconnected (physical proximity) or the lan78xx driver to be unloaded to exploit. | |
rodrigo-zaiden | issue observed when device is disconnected or driver unloaded. a regression was reported in Jammy kernel release, version 5.15.0-94.104. the regression could lead the kernel to crash, under the same condition: device removal. hence, the priority is still low when considering the regression. two commits are needed in order to have the regression fixed: 82ed6f7ef58f timers: Replace BUG_ON()s d02e382cef06 timers: Silently ignore timers with a NULL function Jammy release version 5.15.0-106.116 includes the first fix for the regression and the second will be placed in next releases. |
