- Summary
- ice: fix potential NULL pointer deref in error path of ice_set_ringparam()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ice: fix potential NULL pointer deref in error path of icesetringparam()
icesetringparam nullifies tstampring of temporary txrings, without clearing ICETXRINGFLAGSTXTIME bit. When ICETXRINGFLAGSTXTIME is set and the subsequent icesetuptx_ring() call fails, a NULL pointer dereference could happen in the unwinding sequence:
icecleantxring() -> iceistxtimecfg() == true (ICETXRINGFLAGSTXTIME is set) -> icefreetxtstampring() -> icefreetstampring() -> tstampring->desc (NULL deref)
Clear ICETXRINGFLAGSTXTIME bit to avoid the potential issue.
Note that this potential issue is found by manual code review. Compile test only since unfortunately I don't have E830 devices.
