https://notcve.org/view.php?id=CVE-2020-36386
An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.8.1. El archivo net/bluetooth/hci_event.c presenta una lectura fuera de límites en la función hci_extended_inquiry_result_evt, también se conoce como CID-51c19bf3d5cf A flaw out of bounds memory access in the Linux kernel bluetooth subsystem was found in the way when some data being read about the bluetooth device with the hci_extended_inquiry_result_evt call. A local user could use this flaw to crash the system or read some data out of memory bounds that can lead to data confidentiality threat. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.8.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=51c19bf3d5cfaa66571e4b88ba2a6f6295311101 https://sites.google.com/view/syzscope/kasan-slab-out-of-bounds-read-in-hci_extended_inquiry_result_evt https://syzkaller.appspot.com/bug?id=4bf11aa05c4ca51ce0df86e500fce486552dc8d2 https://syzkaller.appspot.com/text?tag=ReproC&x=15ca2f46900000 https://access.redhat.com/security/cve/CVE-2020-36386 https://bugzilla.redhat.com&# • CWE-125: Out-of-bounds Read •
