Linux kernel security vulnerabilities

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 memory leak in the iommu/vt-d module intelsetupirqremapping...

PT-2024-9283

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to an infinite loop in the IRQ handler upon power fault in the Linux kernel's PCI: pciehp component. The Power Fault Detected bit in the Slot Status register is...

DEBIAN-CVE-2024-38613

In the Linux kernel, the following vulnerability has been resolved: m68k: Fix spinlock race in kernel thread creation Context switching does take care to retain the correct lock owner across the switch from 'prev' to 'next' tasks. This does rely on interrupts remaining disabled for the entire...

DEBIAN-CVE-2024-38607

In the Linux kernel, the following vulnerability has been resolved: macintosh/via-macii: Fix "BUG: sleeping function called from invalid context" The via-macii ADB driver calls requestirq after disabling hard interrupts. But disabling interrupts isn't necessary here because the VIA shift register...

UBUNTU-CVE-2024-38607

In the Linux kernel, the following vulnerability has been resolved: macintosh/via-macii: Fix "BUG: sleeping function called from invalid context" The via-macii ADB driver calls requestirq after disabling hard interrupts. But disabling interrupts isn't necessary here because the VIA shift register...

PT-2024-9643

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.10.0-rc2-syzkaller-g8867bbd4a056 Description The vulnerability is related to a CPU lockup caused by excessive log messages in the cdc-wdm driver. The interrupt-URB completion callback in the driver takes too...

kernel: kvm: Avoid potential UAF in LPI translation cache

A flaw was found in the Linux kernel pertaining to a potential use-after-free UAF scenario in a system involving Logical Partitioning Interrupts LPI translation cache operations. Specifically, the issue arises when a cache hit occurs concurrently with an operation that invalidates the cache, such...

CVE-2023-52740

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s/interrupt: Fix interrupt exit race with security mitigation switch The RFI and STF security mitigation options can flip the interruptexitnotreentrant static branch condition concurrently with the interrupt exit code...

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...

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...

kernel: i2c: i801: Don't generate an interrupt on bus reset

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Don't generate an interrupt on bus reset Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt...

SUSE CVE-2022-2153

A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...

SUSE CVE-2024-36950

In the Linux kernel, the following vulnerability has been resolved: firewire: ohci: mask bus reset interrupts between ISR and bottom half In the FireWire OHCI interrupt handler, if a bus reset interrupt has occurred, mask bus reset interrupts until busresetwork has serviced and cleared the...

SUSE CVE-2024-36951

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: range check cp bad op exception interrupts Due to a CP interrupt bug, bad packet garbage exception codes are raised. Do a range check so that the debugger and runtime do not receive garbage codes. Update the user api ...

SUSE CVE-2024-36962

In the Linux kernel, the following vulnerability has been resolved: net: ks8851: Queue RX packets in IRQ handler instead of disabling BHs Currently the driver uses localbhdisable/localbhenable in its IRQ handler to avoid triggering netrxaction softirq on exit from netifrx. The netrxaction could...
