* New CVEs

CVE-2021-39800: Information leak bug in Android ION code

CVSS v3 score is not provided

ION was remove by commit e722a29 ("staging: ion: remove from the
tree") which was merged in 5.11-rc1.
There is a big different between 4.9 and 4.19/5.10 so 4.19 and 5.10
may not have this issue. 4.4 may affected by this issue.
However, no CIP member enables CONFIG_ION in 4.4 kernel.

Fixed status

CVE-2022-1263: Null pointer dereference bug in the kvm module which
can lead to DoS

CVSS v3 score is not provided

Added kvm_dirty_ring_free() in kvm_vcpu_destroy() was commit fb04a1e
("KVM: X86: Implement ring-based dirty memory tracking") that was
merged in 5.11-rc1. So, earlier than 5.11 kernels may not be affected
by this vulnerability.

Fixed status

Fixed in kvm tree as of
2022/04/08(https://www.spinics.net/lists/kvm/msg273052.html).

CVE-2022-1158: KVM: x86/mmu: do compare-and-exchange of gPTE via the
user address

CVSS v3 score is not provided

Reporter said that "/dev/kvm is accessible by unprivileged local
users, so a userspace process
may leverage this bug to corrupt the kernel, resulting in a denial of
service condition or potentially achieving privilege escalation. But, since
the write is a compare-and-exchange operation that only updates the
Access/Dirty bit, we don't think exploiting this single bug will be easy.".

This vulnerability was introduced by commit bd53cb3 (X86/KVM: Handle
PFNs outside of kernel reach when touching GPTEs) was merged in
5.2-rc1 so that 4.x kernels are not affected by this issue.

CVE-2022-28893: SUNRPC: Ensure we flush any closed sockets before xs_xprt_free()

CVSS v3 score is not provided

The SUNRPC subsystem in the Linux kernel through 5.17.2 can call
xs_xprt_free before ensuring that sockets are in the intended state.

CVE-2022-1280: concurrency use-after-free between drm_setmaster_ioctl
and drm_mode_getresources

CVSS v3 score is not provided

The reporter found this bug in 4.19.237. Kernel 5.15 and newer are
already fixed (https://www.openwall.com/lists/oss-security/2022/04/12/4)
but not described which commit(s) fixes this bug.

According to the
PoC(https://www.openwall.com/lists/oss-security/2022/04/12/3), it
needs to open /dev/dri/card0.
However, /dev/dri/card0's permission is following.

crw-rw----+ 1 root video 226, 0 Apr 13 09:15 /dev/dri/card0

So, attacker must have correct privilege to abuse this CVE.

Fixed status

Not fixed yet.
