Message-ID: <2024042858-CVE-2022-48653-b6e7@gregkh> Date: Sun, 28 Apr 2024 15:05:14 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2022-48653: ice: Don't double unplug aux on peer initiated reset Description =========== In the Linux kernel, the following vulnerability has been resolved: ice: Don't double unplug aux on peer initiated reset In the IDC callback that is accessed when the aux drivers request a reset, the function to unplug the aux devices is called. This function is also called in the ice_prepare_for_reset function. This double call is causing a "scheduling while atomic" BUG.

The correct place to unplug the aux devices for a reset is in the prepare_for_reset function, as this is a common place for all reset flows. It also has built in protection from being called twice in a single reset instance before the aux devices are replugged. The Linux kernel CVE team has assigned CVE-2022-48653 to this issue. Affected and fixed versions =========================== Issue introduced in 5.14 with commit f9f5301e7e2d and fixed in 5.15.71 with commit 34447d64b8d2 Issue introduced in 5.14 with commit f9f5301e7e2d and fixed in 5.19.12 with commit 149979e87eb7 Issue introduced in 5.14 with commit f9f5301e7e2d and fixed in 6.0 with commit 23c619190318 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2022-48653 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/intel/ice/ice_main.c 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/34447d64b8d28e4d6a73d73f07c879959d68fbfe https://git.kernel.org/stable/c/149979e87eb7a365d3d0b259bed79d84ff585a93 https://git.kernel.org/stable/c/23c619190318376769ad7b61504c2ea0703fb783
