CVE-2026-89444

CVE-2026-89444 affects the Linux kernel's platform/x86: dell-wmi-sysman driver. The set_attribute() function populates the security area of the BIOS attribute request buffer with the current admin password via populate_security_buffer(), then calls print_hex_dump_bytes() to dump the entire reques...

CVE-2026-89445

CVE-2026-89445 is a Use-After-Free in the Linux kernel 's iommufd selftest component. The TRIGGER_IOPF selftest borrows an attach handle from group->pasid_array without synchronizing against PASID detach, allowing a concurrent iommu_report_device_fault() to dereference a freed struct iommufd_a...

CVE-2026-89443

CVE-2026-89443 affects the Linux kernel's platform/x86 ISST (Intel Speed Select Technology) module . The functions isst_if_get_perf_level_mask() and isst_if_get_base_freq_mask() use a user-provided level parameter as an index into perf_levels[] without first validating it against max_level, unlik...

CVE-2026-89442

CVE-2026-89442 affects the Linux kernel 's platform/x86 ISST (Intelligent Speed and Frequency Tuning) module. The isst_if_clos_assoc() ioctl function improperly validates the user-supplied socket_id: it uses > instead of >= against topology_max_packages(), allowing an out-of-bounds array ac...

CVE-2026-89441

CVE-2026-89441 is a use-after-free vulnerability in the Linux kernel's mmc: via-sdmmc driver. During device removal, a previously queued carddet_work can still execute after via_sd_remove() returns, dereferencing the freed host's MMIO base via container_of(). This can lead to system instability o...

CVE-2026-89440

CVE-2026-89440 affects the Linux kernel's via-sdmmc MMC driver . The root cause is a use-after-free that occurs when mmc_add_host() fails during device probe: the SD card-detect interrupt (request_irq()) remains registered and its handler (via_sdc_isr()) continues to dereference the freed host st...

CVE-2026-89439

CVE-2026-89439 affects the Linux kernel's platform/x86 ISST driver . The vulnerability stems from a missing NULL check on isst_common.sst_inst[] when socket loading fails. The fix adds a NULL check to be consistent with other code paths that already handle this condition. No specific affected ker...

CVE-2026-89438

This CVE affects the Linux kernel 's platform/x86: ISST (Intelligent Speed and Frequency Tuning Technology) driver. The root cause is a missing validation of the maximum CLOS ID and logical CPU ID for the core power feature. These values are used to calculate MMIO offsets , so an out-of-range val...

CVE-2026-89437

CVE-2026-89437 affects the Linux kernel 's platform/x86 int1092 driver. The root cause is a memory leak in sar_probe() : memory allocated for device_mode_info by parse_package() (called via sar_get_data() ) is not freed along certain error paths. The fix converts these allocations to device-manag...

CVE-2026-81018

CVE-2026-81018 is a memory leak in the Linux kernel 's platform/x86: think-lmi driver. When multi-certificate support is active, the system authentication object stores ->signature and ->save_signature, which are not freed when the driver is removed. The fix frees these signatures on driver...

CVE-2026-89436

CVE-2026-89436 is an out-of-bounds write in the Linux kernel's panasonic-laptop driver (platform/x86). In acpi_pcc_retrieve_biosdata(), a trailing sentinel is written at pcc->sinf[hkey->package.count], but when a DSDT's SINF package count equals SQTY+1 (a known off-by-one hardware quirk han...

CVE-2026-81017

CVE-2026-81017 affects the Linux kernel's platform/chrome/sensorhub driver. The root cause is a missing validation of the 8-bit EC-reported sensor number in cros_ec_sensorhub_ring_handler(); the unvalidated value is then used to index sensorhub->batch_state[], an array allocated with only sens...

CVE-2026-81015

A resource leak in the Linux kernel's AMD PMC (Power Management Controller) driver (platform/x86/amd/pmc) occurs when amd_stb_s2d_init() fails during probe. The error path leaves the LPS0 s2idle handler registered on the global list and leaks the debugfs directory, while devm-managed resources ar...

CVE-2026-81016

This vulnerability affects the Linux kernel's AMD Platform Management Controller (PMC) driver (platform/x86/amd/pmc). The function amd_stb_s2d_init() discards return values from several S2D SMU commands. When the SMU refuses a command, the S2D_PHYS_ADDR_LOW/HIGH return values are ignored, leaving...

CVE-2026-81014

CVE-2026-81014 is a heap out-of-bounds read in the Linux kernel's platform/x86: hp-bioscfg driver, affecting the sk_store() and kek_store() sysfs write handlers. Both functions strip a trailing newline from user input and allocate a key buffer of size length (one byte shorter), but then pass the ...

CVE-2026-81012

CVE-2026-81012 is an off-by-one write in the Linux kernel's platform/x86: hp-bioscfg driver. The function hp_get_string_from_buffer() uses a strict greater-than (>) comparison when clamping the converted string length against the destination buffer size. When the converted length is exactly eq...

CVE-2026-81013

CVE-2026-81013 is a heap out-of-bounds read in the Linux kernel's hp-bioscfg platform driver. The root cause is in validate_password_input(), which computes length = strlen(buf) and then checks buf[length - 1] to strip a trailing newline without first verifying that length is nonzero. Writing a b...

CVE-2026-81011

CVE-2026-81011 affects the Linux kernel's hp-bioscfg platform driver (platform/x86). The per-type package parsers derive the element count from elements[0] (the ACPI NAME field, always a string) rather than the validated obj->package.count, causing them to bound against the name string length ...

CVE-2026-81009

CVE-2026-81009 affects the Linux kernel in the io_uring/query subsystem. The function io_handle_query_entry() clamps hdr.size for the inbound copy_from_user() but retains the original user-supplied value as usize. When passed to copy_struct_to_user(), an oversized usize triggers clear_user() on t...

CVE-2026-81010

CVE-2026-81010 affects the Linux kernel's io_uring/waitid component. The function io_waitid_cb() fails to honor the tw.cancel flag when executed via the fallback task_work path from a kworker, causing __do_wait() to run in the wrong task context. Because waitid is task-context dependent, child lo...
