Title: [SRU][Ubuntu 22.04.1]: Observed "Array Index out of bounds" Call Trace multiple times on Ubuntu 22.04.1 OS during boot Status in linux package in Ubuntu: In Progress Status in linux source package in Jammy: Fix Released Status in linux source package in Kinetic: Fix Committed Bug description: SRU Justification: [Impact] When booted into Ubuntu 22.04.1 OS after installation, observed "Array Index out of bounds" Call Trace multiple times in dmesg. Call Trace is as follow: [ 6.125704] UBSAN: array-index-out-of-bounds in /build/linux-JjvoxS/linux-5.15.0/drivers/scsi/megaraid/megaraid_sas_fp.c:103:32 [ 6.125705] index 1 is out of range for type 'MR_LD_SPAN_MAP [1]' [ 6.125707] CPU: 0 PID: 18 Comm: kworker/0:1 Not tainted 5.15.0-53-generic #59-Ubuntu [ 6.125709] Hardware name: Dell Inc. , BIOS 11/08/2022 [ 6.125710] Workqueue: events work_for_cpu_fn [ 6.125716] Call Trace: [ 6.125718] <TASK> [ 6.125720] show_stack+0x52/0x5c [ 6.125725] dump_stack_lvl+0x4a/0x63 [ 6.125731] dump_stack+0x10/0x16 [ 6.125732] ubsan_epilogue+0x9/0x49 [ 6.125734] __ubsan_handle_out_of_bounds.cold+0x44/0x49 [ 6.125736] ?

Connect PERC H355 controller to the system 2. Create RAID1 using drives connected to PERC Controller 3. Install Ubuntu 22.04.1 on VD 4. Boot into OS after installation 5. Multiple Call Traces of "array-index-out-of-bounds" are seen Expected Behavior: OS should boot without this Call Trace [Fix] [PATCH v3 0/6] Replace one-element arrays with flexible-array members https://lore.kernel.org/linux-hardening/cover.1660592640.git.gustavo...@kernel.org/ 48658213 scsi: megaraid_sas: Use struct_size() in code related to struct MR_PD_CFG_SEQ_NUM_SYNC 41e83026 scsi: megaraid_sas: Use struct_size() in code related to struct MR_FW_RAID_MAP ee92366a scsi: megaraid_sas: Replace one-element array with flexible- array member in MR_PD_CFG_SEQ_NUM_SYNC eeb3bab7 scsi: megaraid_sas: Replace one-element array with flexible- array member in MR_DRV_RAID_MAP 204a29a1 scsi: megaraid_sas: Replace one-element array with flexible- array member in MR_FW_RAID_MAP_DYNAMIC ac23b92b scsi: megaraid_sas: Replace one-element array with flexible- array member in MR_FW_RAID_MAP [Test Plan] 1. Connect PERC H355 controller to the system 2. Create RAID1 using drives connected to PERC Controller 3. Install Ubuntu 22.04.1 on VD 4. Boot into OS after installation OS should boot without the Call Trace listed in the Impact field [Where problems could occur] [Other Info] https://code.launchpad.net/~mreed8855/ubuntu/+source/linux/+git/jammy/+ref/array_bounds_lp_2008157 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2008157/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
