| Subject: CVE-2024-53048: ice: fix crash on probe for DPLL enabled E810 LOM |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ice: fix crash on probe for DPLL enabled E810 LOM |
| |
| The E810 Lan On Motherboard (LOM) design is vendor specific. Intel |
| provides the reference design, but it is up to vendor on the final |
| product design. For some cases, like Linux DPLL support, the static |
| values defined in the driver does not reflect the actual LOM design. |
| Current implementation of dpll pins is causing the crash on probe |
| of the ice driver for such DPLL enabled E810 LOM designs: |
| |
| WARNING: (...) at drivers/dpll/dpll_core.c:495 dpll_pin_get+0x2c4/0x330 |
| ... |
| Call Trace: |
| <TASK> |
| ? __warn+0x83/0x130 |
| ? dpll_pin_get+0x2c4/0x330 |

| ? dpll_pin_get+0x117/0x330 |
| ice_dpll_get_pins.isra.0+0x52/0xe0 [ice] |
| ... |
| |
| The number of dpll pins enabled by LOM vendor is greater than expected |
| and defined in the driver for Intel designed NICs, which causes the crash. |
| |
| Prevent the crash and allow generic pin initialization within Linux DPLL |
| subsystem for DPLL enabled E810 LOM designs. |
| |
| Newly designed solution for described issue will be based on "per HW |
| design" pin initialization. It requires pin information dynamically |
| acquired from the firmware and is already in progress, planned for |
| next-tree only. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53048 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/82b107a27bab29146e159b6b9f21146c97c45a53 |
