hw: amd: Instruction raise #VC exception at exit

A vulnerability was found in AMD SEV-SNP, where a malicious hypervisor can potentially break confidentiality and integrity of SEV-SNP on Linux guests by injecting interrupts. An attacker can inject interrupt 0x80, which is used by Linux for legacy 32-bit system calls, and arbitrarily change the...

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 not refreshing the asynchronous PF work queue when the vCPU is destroyed...

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...

mod_cluster/mod_proxy_cluster: Stored Cross site Scripting

A flaw was found in the modproxycluster in the Apache server. This issue may allow a malicious user to add a script in the 'alias' parameter in the URL to trigger the stored cross-site scripting XSS vulnerability. By adding a script on the alias parameter on the URL, it adds a new virtual host an...

kernel: KVM: SVM: Get source vCPUs from source VM for SEV-ES intrahost migration

A flaw was found in the Linux kernel's KVM SVM implementation for AMD SEV-ES. During intrahost VM migration, KVM incorrectly retrieves source vCPUs from the destination VM instead of the source VM. This causes the VMSA Virtual Machine Save Area pointer to remain NULL, leading to a host kernel cra...

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: drm/amdgpu: unmap and remove csa_va properly

A locking violation was found in the Linux kernel's AMD GPU driver in the context save area cleanup path. A local user can trigger this issue when closing GPU contexts, causing the driver to unmap and remove virtual memory mappings without first reserving the root page directory buffer object. Th...

kernel: use after free in vcs_read in drivers/tty/vt/vc_screen.c due to race

A use-after-free flaw was found in vcsread in drivers/tty/vt/vcscreen.c in vcscreen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information...

kernel: vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF

In the Linux kernel, the following vulnerability has been resolved: vcscreen: move load of struct vcdata pointer in vcsread to avoid UAF After a call to consoleunlock in vcsread the vcdata struct can be freed by vcdeallocate. Because of that, the struct vcdata pointer load must be done at the top...

kernel: Linux kernel: Information disclosure in VFIO Type1 module via uninitialized stack memory

A flaw was found in the Linux kernel's Virtual Function I/O VFIO Type1 module. This vulnerability allows a local user to expose uninitialized kernel stack memory to userspace, leading to information disclosure. The flaw occurs because a specific data structure, vfioiommutype1infocapmigration,...

kernel: amdgpu: validate offset_in_bo of drm_amdgpu_gem_va

A flaw was found in the AMDGPU graphics driver within the Linux kernel was identified where the offsetinbo parameter in the drmamdgpugemva handler was not sufficiently validated. Under certain conditions, an addition of offsetinbo and mapsize can overflow, resulting in an out-of-bounds access...

kernel: drm/i915: mark requests for GuC virtual engines to avoid use-after-free

A use-after-free vulnerability was found in the Linux kernel Intel i915 graphics driver's GuC virtual engine request handling. A local user with access to GPU rendering can create requests on GuC virtual engines and trap references via syncfile or dmabuf, causing fence release operations to acces...

kernel: i40e: Do not allow untrusted VF to remove administratively set MAC

A flaw was found in Intel network adapters in the Linux kernel, where untrusted virtualized network interfaces can remove MAC addresses set by the system. This flaw allows an attacker with sufficient privileges to cause a denial of service...

kernel: Linux kernel HSR driver: Denial of Service via uninitialized value access

A flaw was found in the High-availability Seamless Redundancy HSR driver within the Linux kernel. A local user can trigger this vulnerability by sending specific Virtual Local Area Network VLAN packets to an HSR interface. This can lead to an uninitialized value being accessed, causing a Denial o...
