kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result
A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...
kernel: netfilter: flowtable: strictly check for maximum number of actions
A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system...
kernel: xen/privcmd: fix double free via VMA splitting
A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...
kernel: Buffer overflow in drivers/xen/sys-hypervisor.c
A flaw was found in the Linux kernel. A buffer overflow vulnerability exists in the Xen hypervisor driver drivers/xen/sys-hypervisor.c. This flaw occurs because the HYPERVISORxenversionXENVERbuildid function returns a build ID that is not properly null-terminated. When the buildidshow function...
kernel: mptcp: fix slab-use-after-free in __inet_lookup_established
