These are the new issues this week:

Best regards,

* 2021-06-04

CVE-2021-33200 -- BPF fix turned out to be buggy.

* 2021-06-09

CVE-2021-0606 -- EoP in GPU DRM Driver / reported by android, probably upstream commit e7cdf5c82f1773c3386b93bbcf13b9bfff29fa31 ... may be interesting?

CVE-2021-3587 -- redhat Bugzilla 1968057: CVE-2021-3587 kernel: nfc: Null pointer dereference in llcp_sock_getname

CVE-2020-36385 -- 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.
According to the CVE-2020-36385.yml, it describes 'RDMA/ucma: Rework
ucma_migrate_id() to avoid races with destroy'. However, the
description of 'An issue was discovered in the Linux kernel before
5.8.1 ...' seems like CVE-2020-36386.

CVE-2020-36387 -- An issue was discovered in the Linux kernel before 5.8.2. fs/io_uring.c has a use-after-free related to io_async_task_func and ctx reference holding, aka CID-6d816e088c35.
