kernel: wifi: mac80211: Discard Beacon frames to non-broadcast address

A beacon protection bypass vulnerability was found in the Linux kernel's mac80211 WiFi stack. According to IEEE 802.11-2020, beacon frames must be sent to the broadcast address, but mac80211 incorrectly accepts unicast beacon frames with the Protected Frame bit set to 1. This allows attackers to...

kernel: net: qrtr: fix refcount saturation and potential UAF in qrtr_port_remove

A flaw was found in the Linux kernel's qrtr network subsystem. A race condition exists in the qrtrportremove function where the socket reference count is decremented prematurely. This allows a concurrent reader to access a socket whose reference count has dropped to zero, potentially leading to a...

kernel: KVM: nSVM: Always use vmcb01 in VMLOAD/VMSAVE emulation

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nSVM module. When a nested virtual machine L2 guest executes VMSAVE/VMLOAD instructions, and these are not intercepted by the first-level hypervisor L1, KVM incorrectly uses vmcb02 instead of vmcb01 for managing guest state...

kernel: scsi: scsi_transport_fc: Widen FPIN pname walker counter to u32

A flaw was found in the Linux kernel's Fibre Channel FC transport component. An adjacent Fibre Channel fabric actor, such as a compromised switch or fabric controller, can send a specially crafted FPIN ELS Fabric Performance Incentive Notification Extended Link Service frame. This malformed frame...

kernel: scsi: libiscsi_tcp: Bound SCSI Response data segment to the connection buffer

A flaw was found in the Linux kernel's libiscsitcp component. A remote attacker, acting as a malicious iSCSI target, could send a specially crafted iSCSI SCSI Command Response ISCSIOPSCSICMDRSP with an oversized data segment. This could lead to a buffer overflow in a fixed-size buffer, potentiall...

kernel: dm-verity: fix buffer overflow in FEC calculation

A flaw was found in the dm-verity component of the Linux kernel. A buffer overflow occurs during Forward Error Correction FEC calculation, allowing an attacker to write past the end of an allocated buffer. This out-of-bounds write can corrupt the syndrome buffer, potentially leading to system...

kernel: EDAC/bluefield: Fix potential integer overflow

In the Linux kernel, the following vulnerability has been resolved: EDAC/bluefield: Fix potential integer overflow The 64-bit argument for the "get DIMM info" SMC call consists of memctrlidx left-shifted 16 bits and OR-ed with DIMM index. With memctrlidx defined as 32-bits wide the left-shift...

kernel: Linux kernel: ath9k Wi-Fi driver use-after-free vulnerability leading to system crash

A flaw was found in the ath9k Wi-Fi driver in the Linux kernel. A race condition exists during the asynchronous firmware loading process and device disconnection. A local attacker, by repeatedly connecting and disconnecting a malicious USB Wi-Fi device that fails firmware download, could trigger ...

kernel: wifi: nl80211: reject oversized EMA RNR lists

A flaw was found in the Linux kernel's nl80211 Wi-Fi subsystem. The nl80211parsernrelems function, responsible for parsing EMA RNR Enhanced Multiple Access Reduced Neighbor Report lists, does not properly handle an excessive number of nested NL80211ATTREMARNRELEMS inputs. This improper input...

kernel: blk-cgroup: fix UAF in __blkcg_rstat_flush()

A flaw was found in the Linux kernel's block input/output control group blk-cgroup component. This vulnerability, a Use-After-Free UAF, occurs when multiple block control groups are released at the same time. A race condition allows one group to remove another's entries while it is still in use,...

kernel: net: qrtr: restrict socket creation to the initial network namespace

A flaw was found in the Linux kernel's QRTR Qualcomm IPC Router networking component. An unprivileged local attacker can create a QRTR socket in a separate network namespace. Due to improper handling of global state variables, this allows the attacker to send datagrams and control-plane messages ...

kernel: wifi: mac80211: capture fast-RX rate before mesh reuses skb->cb

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This use-after-free vulnerability arises from incorrect handling of fast-RX rate data during mesh processing. This can lead to memory corruption, which an attacker could potentially exploit to cause a system crash denial of service...
