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 platform/chrome: sensorhub: Bound the EC-reported sensor number

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: sensorhub: Bound the EC-reported sensor number Each EC FIFO event carries an 8-bit sensor number in-sensornum. crosecsensorhubringhandler validates the FIFO event count, the per-read count and the ring bound, but...

CVE-2026-81017

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: sensorhub: Bound the EC-reported sensor number Each EC FIFO event carries an 8-bit sensor number in-sensornum. crosecsensorhubringhandler validates the FIFO event count, the per-read count and the ring bound, but...

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-2026-81014 platform/x86: hp-bioscfg: fix heap OOB read in sk_store() and kek_store()

In the Linux kernel, the following vulnerability has been resolved: platform/x86: hp-bioscfg: fix heap OOB read in skstore and kekstore skstore and kekstore strip a trailing newline from the sysfs write before allocating the key buffer: length = count; if buflength - 1 == '\n' length--;...

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 ...
