kernel: untrusted VMM can trigger int80 syscall handling

A flaw was found in the Linux kernel. A VMM can inject external interrupts on any arbitrary vector at any time, which may allow the guest OS to be manipulated from the VMM side...

kernel: net/mlx5e: Move representor neigh cleanup to profile cleanup_tx

A flaw was identified in the Linux kernel’s Mellanox mlx5 Ethernet driver net/mlx5e related to the cleanup order of neighbour information when handling offloaded IP tunnel encapsulation rules in ECMP Equal-Cost Multipath mode. In certain scenarios — such as unloading the eswitch device while an...

kernel: ipv4: NULL pointer dereference in ipv4_send_dest_unreach()

A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer skb was assumed to be associated with a device before calling ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...

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 stems from the fact that a tasklet may hang on to another kernel, racing to remove irq...

Lazarus Hackers Exploited Windows Kernel Flaw as Zero-Day in Recent Attacks

The notorious Lazarus Group actors exploited a recently patched privilege escalation flaw in the Windows Kernel as a zero-day to obtain kernel-level access and disable security software on compromised hosts. The vulnerability in question is CVE-2024-21338 CVSS score: 7.8, which can permit an...

Design/Logic Flaw

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race between transaction aborts and fsyncs leading to use-after-free There is a race between a task aborting a transaction during a commit, a task doing an fsync and the transaction kthread, which leads to an...

kernel: NULL pointer dereference in nvmet_tcp_build_iovec

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service...

kernel: hid: Use After Free in asus_remove()

A use-after-free flaw was found in asuskbdbacklightset in drivers/hid/hid-asus.c in the Linux Kernel. This issue could allow an attacker to crash the system when plugging in or disconnecting a malicious USB device, which may lead to a kernel information leak problem...

kernel: use-after-free in smb2_is_status_io_timeout()

A use-after-free flaw was found in smb2isstatusiotimeout in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region,...

kernel: UAF during login when accessing the shost ipaddress

A use-after-free flaw was found in iscsiswtcpsessioncreate in drivers/scsi/iscsitcp.c in the SCSI sub-component in the Linux Kernel. This issue could allow an attacker to leak kernel internal information...

DEBIAN-CVE-2023-6531

A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unixstreamreadgeneric on the socket that the SKB is queued on...

CVE-2024-0562 Kernel: use-after-free after removing device in wb_inode_writeback_end in mm/page-writeback.c

A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdiunregister is called to stop further write-back and waits for associated delayed work to complete. However, wbinodewritebackend may schedule bandwidth estimation work after this has completed, which can result in the...

CVE-2024-0443

A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgrouprstatflush is only called at cssreleaseworkfn, which is called when the blkcg reference count reaches 0. This circula...
