- Summary
- CVE-2024-38553 affecting package kernel 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved:
net: fec: remove .ndopollcontroller to avoid deadlocks
There is a deadlock issue found in sungem driver, please refer to the commit ac0a230f719b ("eth: sungem: remove .ndopollcontroller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disableirq() is called by .ndopollcontroller interface of sungem driver, however, disableirq() might sleep. After analyzing the implementation of fecpollcontroller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndopollcontroller is unnecessary to be implemented in the fec driver, so fecpollcontroller() can be safely removed.
