In do_epoll_ctl and ep_loop_check_proc of eventpoll.c, there is a possible use after free due to a logic error. This could lead to local escalation of privilege with no additional execution privileges needed.(CVE-2020-0466) In the l2tp subsystem, there is a possible use after free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed.(CVE-2020-27067) In the nl80211_policy policy of nl80211.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed.(CVE-2020-27068) In audit_free_lsm_field of auditfilter.c, there is a possible bad kfree due to a logic error in audit_data_to_entry. This could lead to local escalation of privilege with no additional execution privileges needed.(CVE-2020-0444) In various methods of hid-multitouch.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed.(CVE-2020-0465) Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field.(CVE-2020-15436) The Linux kernel before version 5.8 is vulnerable to a NULL pointer dereference in drivers/tty/serial/8250/8250_core.c:serial8250_isa_init_ports() that allows local users to cause a denial of service by using the p-serial_in pointer which uninitialized.(CVE-2020-15437) A flaw was found in the Linux kernels implementation of MIDI, where an attacker with a local account and the permissions to issue an ioctl commands to midi devices, could trigger a use-after-free. A write to this specific memory while freed and before use could cause the flow of execution to change and possibly allow for memory corruption or privilege escalation.(CVE-2020-27786) Array index out of bounds access when setting extended attributes on journaling filesystems.(CVE-2020-27815) NULL-ptr deref in the spk_ttyio_receive_buf2() function in spk_ttyio.c(CVE-2020-27830) An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check, aka CID-c444eb564fb1.(CVE-2020-29368) An issue was discovered in kmem_cache_alloc_bulk in mm/slub.c in the Linux kernel before 5.5.11. The slowpath lacks the required TID increment, aka CID-fd4d9c7d0c71.(CVE-2020-29370) An issue was discovered in romfs_dev_re ... Description truncated. Please see the references for more information.
