Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that originates from a dentry leak in the cachefiles subsystem in the cachefilesopenfile function, which could lead to...

kernel: wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values

A vulnerability was found in the cfg80211 component in the Linux kernel, where a lack of proper range validation applied to the NL80211ATTRTXQQUANTUM can lead to a scenario where the userspace passes an extremely high value that the kernel is not designed to handle efficiently ex. 2^31. This can...

kernel: mm: avoid overflows in dirty throttling logic

A vulnerability was found in the Linux kernel's memory management subsystem where a lack of proper size checks on dirty limits can lead to situations where large dirty limits end up being larger than 32-bits, resulting in potential overflows and divisions by 0. This can cause memory corruption,...

kernel: PCI/PM: Drain runtime-idle callbacks before driver removal

A vulnerability was found in the PCI subsystem in the Linux kernel, where runtime-idle callbacks are not always drained before a PCI driver is removed. If these callbacks are still active when the driver is removed, it could result in system instability or crashes...

kernel: ice: Fix improper extts handling

A vulnerability was found in the Linux kernel's ethernet ice driver, where EXTTS events are improperly handled. If the driver is removed while the managing application is running, certain EXTT events might remain enabled. This issue can lead to system instability and crashes...

This can...

kernel: ppp: reject claimed-as-LCP but actually malformed packets

The vulnerability was found in the Linux kernel's ppp pppgeneric.c driver, in the pppread and pppwrite functions where malformed packets were erroneously identified as LCP packets, leading to potential issues with packet handling. This flaw could potentially lead to system instability...

kernel: nvmet: fix a possible leak when destroy a ctrl during qp establishment

A vulnerability was found in the Linux kernel's nvme driver. A lack of proper checks can lead to a race condition during the destruction of a queue pair when a controller is being established. This issue can lead to system instability or crashes...

kernel: PCI/PM: Drain runtime-idle callbacks before driver removal

A vulnerability was found in the PCI subsystem in the Linux kernel, where runtime-idle callbacks are not always drained before a PCI driver is removed. If these callbacks are still active when the driver is removed, it could result in system instability or crashes...

kernel: hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs

A vulnerability was found in the Linux kernel's hwmon subsystem, specifically in the mlxreg-fan driver. The issue arises when the driver’s sysfs interface for controlling fan speed does not properly handle cases where the requested minimum fan speed exceeds the maximum allowable value. When the...

kernel: ppp: reject claimed-as-LCP but actually malformed packets

The vulnerability was found in the Linux kernel's ppp pppgeneric.c driver, in the pppread and pppwrite functions where malformed packets were erroneously identified as LCP packets, leading to potential issues with packet handling. This flaw could potentially lead to system instability...

kernel: netfilter: bridge: confirm multicast packets before passing them up the stack

A security vulnerability was identified in the Linux kernel's netfilter subsystem, specifically affecting the handling of multicast and broadcast packets on network bridges. The issue arises from a race condition in the connection tracking conntrack module when processing cloned socket buffers sk...

kernel: net: ntb_netdev: Move ntb_netdev_rx_handler() to call netif_rx() from __netif_rx()

A vulnerability was found in the Linux kernel in the ntbnetdevrxhandler function which calls the function netifrx, which can only be called from interrupt context, in a preemptible context. This vulnerability can lead to potential race conditions and system instability...

kernel: mm/hugetlb: fix missing hugetlb_lock for resv uncharge

CVE-2024-36000 addresses a synchronization issue in the Linux kernel's management of huge pages. The problem arises when multiple threads modify the reservation map concurrently without proper locking, leading to potential inconsistencies and system instability...

Linux kernel resource misallocation vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. The Linux kernel suffers from a resource misallocation vulnerability that stems from an issue with forced large page alignment on 32-bit systems.Due to the constrained virtual...

kernel: net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()

A vulnerability was found in the icebridgesetlink function in the Linux kernel. A missing check to verify whether the nlmsgfindattr function returns NULL or not could lead to a NULL pointer dereference, system instability, or crashes...
