kernel: netfilter: nf_tables: disallow anonymous set with timeout flag

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: disallow anonymous set with timeout flag Anonymous sets are never used with timeout from userspace, reject this. Exception to this rule is NFTSETEVAL to ensure legacy meters still work...

kernel: netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout

A vulnerability was found in the netfilter/nftables subsystem of Linux Kernel, where a race condition caused where the garbage collector could prematurely collect elements from anonymous sets with timeouts while they were being released...

CVE-2024-21512

Versions of the package mysql2 before 3.9.8 are vulnerable to Prototype Pollution due to improper user input sanitization passed to fields and tables when using nestTables...

kernel: netfilter: nf_tables: netlink notifier might race to release objects

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: netlink notifier might race to release objects commit release path is invoked via callrcu and it runs lockless to release the objects after rcu grace period. The netlink notifier handler might win race to...

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

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: do not allow SETID to refer to another table When doing lookups for sets on the same batch by using its ID, a set from a different table can be used. Then, when the table is removed, a reference to the set ma...

kernel: netfilter: nf_tables: possible module reference underflow in error path

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: possible module reference underflow in error path dst-ops is set on when nftexprclone fails, but module refcount has not been bumped yet, therefore nftexprdestroy leads to module reference underflow...

kernel: netfilter: nf_tables: fix underflow in chain reference counter

A flaw was found in the Linux kernel's netfilter nftables component. During set element addition, an error path incorrectly decrements the chain reference counter twice. This reference count underflow could potentially lead to a use-after-free condition when the chain is subsequently freed while...

kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function

A flaw was found in the Netfilter subsystem in the Linux kernel. This issue occurs in the nftverdictinit function, allowing positive values as a drop error within the hook verdict, therefore, the nfhookslow function can cause a double-free vulnerability when NFDROP is issued with a drop error tha...
