kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation

A use-after-free flaw was found in nftables cross-table in the net/netfilter/nftablesapi.c 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...

kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region

A flaw was found in KVM. When updating a guest's page table entry, vmpgoff was improperly used as the offset to get the page's pfn. As vaddr and vmpgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and...

kernel: vsock: remove vsock from connected table when connect is interrupted by a signal

A vulnerability was found in the Linux kernel's vsock subsystem's vsockstreamconnect function where improper handling of the socket state can lead to the connected table's list being corrupted. This occurs when a signal interrupt occurs and resets the socket's state without removing it from the...

kernel: netfilter: nf_tables: do not allow CHAIN_ID to refer to another table

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: do not allow CHAINID to refer to another table When doing lookups for chains on the same batch by using its ID, a chain from a different table can be used. If a rule is added to a table but refers to a chain ...
