CVE-2025-38499

In the Linux kernel, the following vulnerability has been resolved: cloneprivatemnt: make sure that caller has CAPSYSADMIN in the right userns What we want is to verify there is that clone won't expose something hidden by a mount we wouldn't be able to undo. "Wouldn't be able to undo" may be a...

kernel: xfrm: out-of-bounds read in __xfrm_state_filter_match()

A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged CAPNETADMIN attacker to trigger an out-of-bounds read, potentially leadi...

kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation

A use-after-free vulnerability was found in the Netfilter subsystem of the Linux kernel when processing batch requests to update nftables configuration. This vulnerability can be abused to perform arbitrary reads and writes in kernel memory. A local user with CAPNETADMIN capability could use this...

kernel: UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests

A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel memory. This flaw allows a local user with CAPNETADMIN capability to crash or potentially...

DEBIAN-CVE-2023-3610

A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation.
