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-2026-98333

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When bringing up a wireless interface fails, the system does not reset the radio LED state, leaving an internal throughput timer running. Consequently, when the wireless device is subsequently removed or unregistered,...

CVE-2026-98327

A flaw was found in the Linux kernel's mac80211 wireless mesh networking subsystem. When leaving or stopping a mesh network while a Channel Switch Announcement CSA is still pending, the kernel fails to reset the switch state and release allocated memory. A local privileged user could exploit this...

CVE-2026-98374

A flaw was found in the Linux kernel's TCP networking subsystem. When replacing packet buffers during connection establishment, the kernel frees memory without updating an internal retransmission pointer, resulting in a use-after-free vulnerability. An unprivileged local user can exploit this...

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...

kernel: ipv6: validate extension header length before copying to cmsg

A flaw was found in the Linux kernel's IPv6 networking stack. An unprivileged local user could exploit a vulnerability in how IPv6 extension header lengths are handled. By manipulating these headers using nftables, an attacker can trigger an out-of-bounds read, leading to information disclosure...

kernel: ipv6: fix use-after-free in ip6_finish_output2()

A flaw was found in the Linux kernel's IPv6 networking stack. A use-after-free vulnerability exists in the ip6finishoutput2 function, where a cached pointer to the IPv6 destination address can become stale after memory reallocation. An attacker could potentially exploit this to leak sensitive...
