the fix was in *-24 in proposed and it worked and was confirmed, then *-25 was released _without_ the fix making *-24 redundant (it's gone now).
the bug assignee is mia (probably well deserved seasonal holiday). can someone on the ubuntu kernel team: _please_ fix this mess. the fix in *-24 was confirmed, we need it put in a _released_ kernel! also the workaround of turning off trackpoint/trackpad was mentioned several times earlier in this bug history. if you search for it or click "See full activity log" at the bottom of the page you will find it there. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1945590 Title: Thinkpad E14 Gen2: Kernel panic with trackpad and trackpoint enabled Status in linux package in Ubuntu: Confirmed Status in linux source package in Impish: Fix Committed Status in linux source package in Jammy: Confirmed Bug description: [Impact] On some thinkpads we may get a kernel panic at boot, because the elantech driver (trakcpad) can trigger out-of-bounds access in the stack. [Test case] Simply boot the kernel on one of the affected systems (e.g., Thinkpad E14 Gen2). [Fix] Prevent the stack out of bound access by applying the following upstream commit (from linux-next): 1d72d9f960cc ("Input: elantech - fix stack out of bound access in elantech_change_report_id()") [Regression potential] The fix is touching the elantech driver, so we could only see regressions with this specific trackpad/mouse driver. [Original bug report] I installed the Ubuntu 21.10 beta and as soon as I boot I get the kernel panic that I am attaching. I also installed Ubuntu 21.04 and upgraded, as soon as I boot with the 5.13 kernel I get the same problem, disabling the trackpad and trackpoint in the bios the problem disappears. Everything works with the 5.11 kernel. I remain available for further details and sorry for my lack of experience.
