CVE-2024-26991

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: x86: Don't overflow lpageinfo when checking attributes Fix KVMSETMEMORYATTRIBUTES to not overflow lpageinfo array and trigger KASAN splat, as seen in the privatememconversionstest selftest. When memory attributes ar...

CVE-2024-26991

The Linux kernel is vulnerable to a vmalloc out-of-bounds read within the KVM x86/mmu component. The issue occurs because the KVM_SET_MEMORY_ATTRIBUTES ioctl operation utilizes an optimization in the hugepage_has_attrs() helper function. While level-1 huge pages are checked first to determine if ...

PT-2024-21607

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the KVM Kernel-based Virtual Machine component of the Linux kernel. It occurs when memory attributes are set on a GFN Guest Frame Number range, and the range has...

UBUNTU-CVE-2021-47034

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Fix pte update for kernel memory on radix When adding a PTE a ptesync is needed to order the update of the PTE with subsequent accesses otherwise a spurious fault may be raised. radixsetpteat does not do this for...

PT-2024-8366

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to insufficient input validation in the riscv component of the Linux kernel. This can lead to a denial of service when the code to patch lies outside the exit sectio...

kernel: ACPI: APEI: Fix integer overflow in ghes_estatus_pool_init()

In the Linux kernel, the following vulnerability has been resolved: ACPI: APEI: Fix integer overflow in ghesestatuspoolinit Change numghes from int to unsigned int, preventing an overflow and causing subsequent vmalloc to fail. The overflow happens in ghesestatuspoolinit when calculating len duri...

kernel: cifs: fix oops during encryption

An out-of-bounds memory access vulnerability exists in the linux kernel, such that A stack-allocated buffer backed by vmalloc was passed into crypto code scatterwalkmapandcopy → memcpy where a cross-page write occurred. This ended up hitting a read-only mapping, causing a page-level fault and...

PT-2025-18602

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A vulnerability in the Linux kernel has been resolved, specifically an integer overflow in the ghes estatus pool init function. The issue occurs when calculating len during the execution...

PT-2025-53190

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.5.0-rc4-rt2-yocto-preempt-rt+ 15 Description The Linux kernel contained a flaw related to memory information dumping within the RCU Read-Copy-Update subsystem. Specifically, when call rcu was invoked multiple...

PT-2024-11867

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue arises from the EFI page table being initially created as a copy of the kernel page table. When VMAP STACK is enabled, kernel stacks are allocated in the vmalloc area. If the...
