CVE-2026-89477

CVE-2026-89477 is a NULL pointer dereference in the Linux kernel's SCTP stream reconfiguration code. When a reconfiguration request is queued in asoc->strreset_chunk but not yet transmitted, chunk->transport remains NULL; three completion functions (sctp_process_strreset_outreq, sctp_proces...

CVE-2026-89466

CVE-2026-89466 is an out-of-bounds read in the Linux kernel's qcom_battmgr power supply driver (Qualcomm battery manager). The function qcom_battmgr_sc8280xp_strcpy() copies firmware-provided strings for model_number , serial_number , and oem_info without a null terminator when the firmware does ...

EUVD-2026-76372

In the Linux kernel, the following vulnerability has been resolved: power: supply: qcombattmgr: terminate the strings from firmware The qcombattmgrsc8280xpstrcpy takes a Pascal-style string when the firmware sends one. Otherwise it copies all BATTMGRSTRINGLEN bytes and leaves the destination...

CVE-2026-89460 s390/cpum_cf: Handle CPU hotplug via prepare/dead callbacks

In the Linux kernel, the following vulnerability has been resolved: s390/cpumcf: Handle CPU hotplug via prepare/dead callbacks The command 'perf stat -e cycles -- ' crashes the kernel when CPUs are hotplug added during that run. Root cause is the allocation of struct cpucfevents at first event...

CVE-2026-89460

CVE-2026-89460 affects the Linux kernel on s390 systems using the CPUMF (Command Processor Measurement Facility) PMU driver. The root cause is that per-CPU cpu_cf_events structures are allocated only for CPUs online at event-creation time. If a CPU is hotplugged online during a perf stat run with...

CVE-2026-89457

CVE-2026-89457 affects the s390/dasd subsystem in the Linux kernel. During dasd_generic_set_online(), a device's discipline is assigned before check_device() allocates device->private. Several sysfs show/store handlers dereference this pointer without a null check, so an unprivileged read of a...
