Vulnerability Summary

An issue exists in the Linux kernel prior to 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against attackers with the stated "When modifying the block device while it is mounted by the filesystem" access.

Vendor Advisories

A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_apic function in the Linux kernel This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation (CVE-2022-2586) A heap buffer overflow flaw was found in the Linux ...
A flaw was found in the x86 KVM subsystem in kvm_steal_time_set_preempted in arch/x86/kvm/x86c in the Linux kernel Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED situations (CVE-2022-39189) A denial of service problem was found, due to a possible recursive lockin ...
In the Linux kernel through 627, fs/ntfs3/inodec has an invalid kfree because it does not validate MFT flags before replaying logs (CVE-2022-48425) A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling This issue results from the improper handling of user-supplied data, which can lead to an assertion fa ...
A flaw was found in the Linux kernel Traffic Control (TC) subsystem Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of ser ...
