CVE-2022-38457 – There is an UAF vulnerability in vmwgfx driver
https://notcve.org/view.php?id=CVE-2022-38457
09 Sep 2022 — A use-after-free(UAF) vulnerability was found in function 'vmw_cmd_res_check' in drivers/gpu/vmxgfx/vmxgfx_execbuf.c in Linux kernel's vmwgfx driver with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).

09 Sep 2022 — An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data.

CVE-2022-39842
https://notcve.org/view.php?id=CVE-2022-39842
05 Sep 2022 — An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur. NOTE: the original discoverer disputes that the overflow can actually happen. Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.19. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.19 • CWE-190: Integer Overflow or Wraparound •
CVE-2022-39188 – kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry
https://notcve.org/view.php?id=CVE-2022-39188
02 Sep 2022 — An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

https://notcve.org/view.php?id=CVE-2022-2590
31 Aug 2022 — A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only shared memory mappings. This flaw allows an unprivileged, local user to gain write access to read-only memory mappings, increasing their privileges on the system.

CVE-2022-3028 – kernel: race condition in xfrm_probe_algs can lead to OOB read/write
https://notcve.org/view.php?id=CVE-2022-3028
31 Aug 2022 — A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.
