CVE-2026-98299

A flaw was found in the Linux kernel's TCP networking subsystem. A privileged local user can cause a Denial of Service DoS by configuring TCP receive buffer limits to an abnormally low value. This improper setting causes the kernel to encounter a division-by-zero error during buffer adjustment...

CVE-2026-98276

A flaw was found in the Linux kernel's networking subsystem. A local attacker can exploit a race condition during concurrent socket operations, such as retrieving timestamps while binding a network socket, because socket flags are modified without proper locking. This issue causes socket memory t...

CVE-2026-98303

A flaw was found in the Linux kernel's IPv4 networking subsystem. When looking up routes to send Internet Control Message Protocol ICMP error messages, the kernel fails to properly reject unreachable input routes. A remote attacker can exploit this flaw by transmitting network packets that trigge...

CVE-2026-90049

A flaw was found in the Linux kernel's networking subsystem. When the skbzerocopy function fails to orphan fragments, it incorrectly calls skbtxerror on the source skbuff skb. This premature completion of the zerocopy user argument and clearing of the SKBFLSHAREDFRAG flag can lead to a condition...

CVE-2026-98101

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition in the ip6mcsource function allows concurrent packet processing routines to observe inconsistent multicast source filter lists when entries are modified in place. A local user could exploit this flaw by changing...

CVE-2026-97984

A flaw was found in the Linux kernel's IPv6 networking subsystem. A local user could cause a Denial of Service DoS by exploiting an integer overflow in the User Datagram Protocol UDP length calculation. When Path MTU Discovery is enabled on a network device configured with an unusually large...

CVE-2026-80977

A flaw was found in the Linux kernel's networking subsystem. The skbtxerror function improperly handles shared zerocopy state in socket buffers skbs. When a cloned skb is processed, it can prematurely signal that its pages are free and drop shared fragment flags while the original skb is still in...
