UBUNTU-CVE-2024-26999

In the Linux kernel, the following vulnerability has been resolved: serial/pmaczilog: Remove flawed mitigation for rx irq flood The mitigation was intended to stop the irq completely. That may be better than a hard lock-up but it turns out that you get a crash anyway if you're using pmaczilog as ...

CVE-2024-27001 comedi: vmk80xx: fix incomplete endpoint checking

In the Linux kernel, the following vulnerability has been resolved: comedi: vmk80xx: fix incomplete endpoint checking While vmk80xx does have endpoint checking implemented, some things can fall through the cracks. Depending on the hardware model, URBs can have either bulk or interrupt type, and...

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 Linux kernel, which stems from a null pointer access vulnerability in the interrupt handler...

kernel: rcu: Avoid stack overflow due to __rcu_irq_enter_check_tick() being kprobe-ed

In the Linux kernel, the following vulnerability has been resolved: rcu: Avoid stack overflow due to rcuirqenterchecktick being kprobe-ed Registering a kprobe on rcuirqenterchecktick can cause kernel stack overflow as shown below. This issue can be reproduced by enabling CONFIGNOHZFULL and bootin...

kernel: irqchip/ti-sci: Fix refcount leak in ti_sci_intr_irq_domain_probe

In the Linux kernel, the following vulnerability has been resolved: irqchip/ti-sci: Fix refcount leak in tisciintrirqdomainprobe ofirqfindparent returns a node pointer with refcount incremented, We should use ofnodeput on it when not needed anymore. Add missing ofnodeput to avoid refcount leak...

kernel: ASoC: codecs: wcd-mbhc-v2: fix resource leaks on component remove

A resource leak was found in the WCD MBHC v2 audio codec driver in the Linux kernel. MBHC resources are not properly released on component probe failure or removal, causing interrupt request failures and preventing successful reprobing of the codec component. This leads to sound card initializati...

kernel: net: phy: dp83822: Fix null pointer access on DP83825/DP83826 devices

A flaw was found in the dp83822 module in the Linux kernel. A private data pointer is only initialized by the DP83822 PHY. It is left uninitialized by other smaller models, allowing a NULL pointer dereference to be triggered due to missing checks when interrupts are being configured, causing a...

kernel: drm/amdgpu/gfx: disable gfx9 cp_ecc_error_irq only when enabling legacy gfx ras

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx: disable gfx9 cpeccerrorirq only when enabling legacy gfx ras gfx9 cpeccerrorirq is only enabled when legacy gfx ras is assert. So in gfxv90hwfini, interrupt disablement for cpeccerrorirq should be executed under...

kernel: drm/amdgpu: drop gfx_v11_0_cp_ecc_error_irq_funcs

A logic error was found in the Linux kernel amdgpu graphics driver's interrupt handling for GFX version 11 hardware. A local user with access to an AMD GPU can trigger a GPU device reset or suspend operation, causing the driver to attempt cleanup of a retired interrupt handler that no longer...

kernel: Linux kernel (amdgpu): Denial of Service via incorrect interrupt handling

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. A local attacker with high privileges could trigger an incorrect interrupt handling mechanism within the gmcv110hwfini function. This issue arises because the host driver attempts to disable an interrupt that is managed by the firmware...

kernel: misc: pci_endpoint_test: Free IRQs before removing the device

A use-after-free flaw was found in the Linux kernel's PCI endpoint test driver. In pciendpointtestremove, IRQs are freed after the device is removed, creating a race window where an IRQ can be delivered after device memory is freed. The IRQ handler then accesses invalid memory, causing a kernel...

kernel: Kernel: Denial of Service in amdgpu driver due to improper interrupt handling

A flaw was found in the Linux kernel's amdgpu graphics driver. A local user with low privileges could exploit this vulnerability due to the improper use of the amdgpuirqput function within the gmcv100hwfini component. This flaw leads to a call trace, which can result in a system crash and a Denia...
