In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkosf: fix out-of-bounds read on option matching In nfosfmatch, the nfosfhdrctx structure is initialized once and passed by reference to nfosfmatchone for each fingerprint checked. During TCP option parsing,...

SUSE CVE-2026-53000

In the Linux kernel, the following vulnerability has been resolved: netfilter: nat: use kfreercu to release ops Florian Westphal says: "Historically this is not an issue, even for normal base hooks: the data path doesn't use the original nfhookops that are used to register the callbacks. However,...

CVE-2026-52999

A flaw was found in the Linux kernel's netfilter subsystem, specifically in the nfnetlinkosf module. When the NFOSFLOGLEVELALL option is configured, an out-of-bounds read vulnerability can occur during TCP option parsing. This issue can lead to incorrect data processing and logging failures,...

CVE-2026-52999

CVE-2026-52999 pertains to the Linux kernel netfilter nfnetlink_osf, where an out-of-bounds read can occur during TCP option parsing when NF_OSF_LOGLEVEL_ALL is enabled. The root cause is a shared ctx->optp pointer that isn’t restored after nf_osf_match_one() returns, allowing subsequent finge...

CVE-2026-52998

CVE-2026-52998 affects the Linux kernel’s netfilter nfnetlink_osf module. The nf_osf_ttl() function can dereference a device pointer (skb->dev) without validating the device, risking a NULL dereference. The patch removes the device dereference and the in_dev_for_each_ifa_rcu loop used to match...
