PT-2024-30730

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the handling of CEQEs in the interrupt handler, which can cause the CPU core to stay in interrupt context too long and lead to soft lockup under heavy load. To...

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...

SUSE CVE-2024-39483

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: WARN on vNMI + NMI window iff NMIs are outright masked When requesting an NMI window, WARN on vNMI support being enabled if and only if NMIs are actually masked, i.e. if the vCPU is already handling an NMI. KVM's ABI fo...

kernel: PCI interrupt mapping cause oops

A denial of service flaw was found in the ARM footbridge in the Linux Kernel. This issue may cause an oops if a PCI driver is loaded or bound after the kernel has initialized...

PT-2024-29750

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.43 Description The issue arises from the idxd driver interrupt completion handler using threaded interrupt, which is not compatible with the hard or soft interrupt context required by netif rx. To resolve thi...

SUSE CVE-2024-39292

In the Linux kernel, the following vulnerability has been resolved: um: Add winch to winchhandlers before registering winch IRQ Registering a winch IRQ is racy, an interrupt may occur before the winch is added to the winchhandlers list. If that happens, registerwinchirq adds to that list a winch...
