CVE-2026-23041 1 Linux 1 Linux Kernel 2026-04-18 N/A
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix NULL pointer crash in bnxt_ptp_enable during error cleanup When bnxt_init_one() fails during initialization (e.g., bnxt_init_int_mode returns -ENODEV), the error path calls bnxt_free_hwrm_resources() which destroys the DMA pool and sets bp->hwrm_dma_pool to NULL. Subsequently, bnxt_ptp_clear() is called, which invokes ptp_clock_unregister(). Since commit a60fc3294a37 ("ptp: rework ptp_clock_unregister() to disable events"), ptp_clock_unregister() now calls ptp_disable_all_events(), which in turn invokes the driver's .enable() callback (bnxt_ptp_enable()) to disable PTP events before completing the unregistration. bnxt_ptp_enable() attempts to send HWRM commands via bnxt_ptp_cfg_pin() and bnxt_ptp_cfg_event(), both of which call hwrm_req_init(). This function tries to allocate from bp->hwrm_dma_pool, causing a NULL pointer dereference: bnxt_en 0000:01:00.0 (unnamed net_device) (uninitialized): bnxt_init_int_mode err: ffffffed KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f] Call Trace: __hwrm_req_init (drivers/net/ethernet/broadcom/bnxt/bnxt_hwrm.c:72) bnxt_ptp_enable (drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:323 drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:517) ptp_disable_all_events (drivers/ptp/ptp_chardev.c:66) ptp_clock_unregister (drivers/ptp/ptp_clock.c:518) bnxt_ptp_clear (drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:1134) bnxt_init_one (drivers/net/ethernet/broadcom/bnxt/bnxt.c:16889) Lines are against commit f8f9c1f4d0c7 ("Linux 6.19-rc3") Fix this by clearing and unregistering ptp (bnxt_ptp_clear()) before freeing HWRM resources.
CVE-2026-23042 1 Linux 1 Linux Kernel 2026-04-18 7.0 High
In the Linux kernel, the following vulnerability has been resolved: idpf: fix aux device unplugging when rdma is not supported by vport If vport flags do not contain VIRTCHNL2_VPORT_ENABLE_RDMA, driver does not allocate vdev_info for this vport. This leads to kernel NULL pointer dereference in idpf_idc_vport_dev_down(), which references vdev_info for every vport regardless. Check, if vdev_info was ever allocated before unplugging aux device.
CVE-2026-23060 1 Linux 1 Linux Kernel 2026-04-17 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - reject too-short AAD (assoclen<8) to match ESP/ESN spec authencesn assumes an ESP/ESN-formatted AAD. When assoclen is shorter than the minimum expected length, crypto_authenc_esn_decrypt() can advance past the end of the destination scatterlist and trigger a NULL pointer dereference in scatterwalk_map_and_copy(), leading to a kernel panic (DoS). Add a minimum AAD length check to fail fast on invalid inputs.
CVE-2026-23062 1 Linux 1 Linux Kernel 2026-04-17 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: platform/x86: hp-bioscfg: Fix kernel panic in GET_INSTANCE_ID macro The GET_INSTANCE_ID macro that caused a kernel panic when accessing sysfs attributes: 1. Off-by-one error: The loop condition used '<=' instead of '<', causing access beyond array bounds. Since array indices are 0-based and go from 0 to instances_count-1, the loop should use '<'. 2. Missing NULL check: The code dereferenced attr_name_kobj->name without checking if attr_name_kobj was NULL, causing a null pointer dereference in min_length_show() and other attribute show functions. The panic occurred when fwupd tried to read BIOS configuration attributes: Oops: general protection fault [#1] SMP KASAN NOPTI KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] RIP: 0010:min_length_show+0xcf/0x1d0 [hp_bioscfg] Add a NULL check for attr_name_kobj before dereferencing and corrects the loop boundary to match the pattern used elsewhere in the driver.

CVE-2026-23084 1 Linux 1 Linux Kernel 2026-04-17 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: be2net: Fix NULL pointer dereference in be_cmd_get_mac_from_list When the parameter pmac_id_valid argument of be_cmd_get_mac_from_list() is set to false, the driver may request the PMAC_ID from the firmware of the network card, and this function will store that PMAC_ID at the provided address pmac_id. This is the contract of this function. However, there is a location within the driver where both pmac_id_valid == false and pmac_id == NULL are being passed. This could result in dereferencing a NULL pointer. To resolve this issue, it is necessary to pass the address of a stub variable to the function.
CVE-2026-23088 1 Linux 1 Linux Kernel 2026-04-17 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: tracing: Fix crash on synthetic stacktrace field usage When creating a synthetic event based on an existing synthetic event that had a stacktrace field and the new synthetic event used that field a kernel crash occurred: ~# cd /sys/kernel/tracing ~# echo 's:stack unsigned long stack[];' > dynamic_events ~# echo 'hist:keys=prev_pid:s0=common_stacktrace if prev_state & 3' >> events/sched/sched_switch/trigger ~# echo 'hist:keys=next_pid:s1=$s0:onmatch(sched.sched_switch).trace(stack,$s1)' >> events/sched/sched_switch/trigger The above creates a synthetic event that takes a stacktrace when a task schedules out in a non-running state and passes that stacktrace to the sched_switch event when that task schedules back in. It triggers the "stack" synthetic event that has a stacktrace as its field (called "stack"). ~# echo 's:syscall_stack s64 id; unsigned long stack[];' >> dynamic_events ~# echo 'hist:keys=common_pid:s2=stack' >> events/synthetic/stack/trigger ~# echo 'hist:keys=common_pid:s3=$s2,i0=id:onmatch(synthetic.stack).trace(syscall_stack,$i0,$s3)' >> events/raw_syscalls/sys_exit/trigger The above makes another synthetic event called "syscall_stack" that attaches the first synthetic event (stack) to the sys_exit trace event and records the stacktrace from the stack event with the id of the system call that is exiting. When enabling this event (or using it in a historgram): ~# echo 1 > events/synthetic/syscall_stack/enable Produces a kernel crash!

CVE-2026-23107 1 Linux 1 Linux Kernel 2026-04-17 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: arm64/fpsimd: signal: Allocate SSVE storage when restoring ZA The code to restore a ZA context doesn't attempt to allocate the task's sve_state before setting TIF_SME. Consequently, restoring a ZA context can place a task into an invalid state where TIF_SME is set but the task's sve_state is NULL. In legitimate but uncommon cases where the ZA signal context was NOT created by the kernel in the context of the same task (e.g. if the task is saved/restored with something like CRIU), we have no guarantee that sve_state had been allocated previously. In these cases, userspace can enter streaming mode without trapping while sve_state is NULL, causing a later NULL pointer dereference when the kernel attempts to store the register state: | # ./sigreturn-za | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 | Mem abort info: | ESR = 0x0000000096000046 | EC = 0x25: DABT (current EL), IL = 32 bits | SET = 0, FnV = 0 | EA = 0, S1PTW = 0 | FSC = 0x06: level 2 translation fault | Data abort info: | ISV = 0, ISS = 0x00000046, ISS2 = 0x00000000 | CM = 0, WnR = 1, TnD = 0, TagAccess = 0 | GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 | user pgtable: 4k pages, 52-bit VAs, pgdp=0000000101f47c00 | [0000000000000000] pgd=08000001021d8403, p4d=0800000102274403, pud=0800000102275403, pmd=0000000000000000 | Internal error: Oops: 0000000096000046 [#1] SMP | Modules linked in: | CPU: 0 UID: 0 PID: 153 Comm: sigreturn-za Not tainted 6.19.0-rc1 #1 PREEMPT | Hardware name: linux,dummy-virt (DT) | pstate: 214000c9 (nzCv daIF +PAN -UAO -TCO +DIT -SSBS BTYPE=--) | pc : sve_save_state+0x4/0xf0 | lr : fpsimd_save_user_state+0xb0/0x1c0 | sp : ffff80008070bcc0 | x29: ffff80008070bcc0 x28: fff00000c1ca4c40 x27: 63cfa172fb5cf658 | x26: fff00000c1ca5228 x25: 0000000000000000 x24: 0000000000000000 | x23: 0000000000000000 x22: fff00000c1ca4c40 x21: fff00000c1ca4c40 | x20: 0000000000000020 x19: fff00000ff6900f0 x18: 0000000000000000 | x17: fff05e8e0311f000 x16: 0000000000000000 x15: 028fca8f3bdaf21c | x14: 0000000000000212 x13: fff00000c0209f10 x12: 0000000000000020 | x11: 0000000000200b20 x10: 0000000000000000 x9 : fff00000ff69dcc0 | x8 : 00000000000003f2 x7 : 0000000000000001 x6 : fff00000c1ca5b48 | x5 : fff05e8e0311f000 x4 : 0000000008000000 x3 : 0000000000000000 | x2 : 0000000000000001 x1 : fff00000c1ca5970 x0 : 0000000000000440 | Call trace: | sve_save_state+0x4/0xf0 (P) | fpsimd_thread_switch+0x48/0x198 | __switch_to+0x20/0x1c0 | __schedule+0x36c/0xce0 | schedule+0x34/0x11c | exit_to_user_mode_loop+0x124/0x188 | el0_interrupt+0xc8/0xd8 | __el0_irq_handler_common+0x18/0x24 | el0t_64_irq_handler+0x10/0x1c | el0t_64_irq+0x198/0x19c | Code: 54000040 d51b4408 d65f03c0 d503245f (e5bb5800) | ---[ end trace 0000000000000000 ]--- Fix this by having restore_za_context() ensure that the task's sve_state is allocated, matching what we do when taking an SME trap.
