USN-7100-2 linux-aws vulnerabilities

Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a deni...

kernel: Linux kernel: ACPICA undefined behavior due to zero offset to null pointer

A flaw was found in ACPICA in the Linux kernel. This vulnerability allows for a denial of service via a null pointer dereference...

kernel: ALSA: timer: Set lower bound of start tick time

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: Set lower bound of start tick time Currently ALSA timer doesn't have the lower limit of the start tick time, and it allows a very small size, e.g. 1 tick with 1ns resolution for hrtimer. Such a situation may lead to ...

kernel: x86/xen: Fix memory leak in xen_smp_intr_init{_pv}()

A memory leak was found in the Linux kernel's Xen SMP interrupt initialization functions for x86 architectures. When interrupt handler binding fails during setup, the error path frees various resources but neglects to free dynamically allocated interrupt name strings created via kasprintf. This...

kernel: arm64: asm-bug: Add .align 2 to the end of __BUG_ENTRY

In the Linux kernel, the following vulnerability has been resolved: arm64: asm-bug: Add .align 2 to the end of BUGENTRY When CONFIGDEBUGBUGVERBOSE=n, we fail to add necessary padding bytes to bugtable entries, and as a result the last entry in a bug table will be ignored, potentially leading to a...

hw: arm64/sme: Always exit sme_alloc() early with existing storage

In the Linux kernel, the following vulnerability has been resolved: arm64/sme: Always exit smealloc early with existing storage When smealloc is called with existing storage and we are not flushing we will always allocate new storage, both leaking the existing storage and corrupting the state. Fi...

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspend The Linux kernel CVE team has assigned CVE-2024-27057 to this issue. Upstream advisory:...

kernel: KVM: arm64: Disassociate vcpus from redistributor region on teardown

A vulnerability was found in the Linux kernel's KVM for ARM64 within the vgic-init.c, vgic-mmio-v3.c, and vgic.h files. The virtual vCPUs may retain dangling pointers in a redistributor region after they have been torn down, leading to potential memory corruption...

kernel: s390/crypto: use vector instructions only if available for ChaCha20

In the Linux kernel, the following vulnerability has been resolved: s390/crypto: use vector instructions only if available for ChaCha20 Commit 349d03ffd5f6 "crypto: s390 - add crypto library interface for ChaCha20" added a library interface to the s390 specific ChaCha20 implementation. However no...

kernel: x86/mm: Fix pti_clone_pgtable() alignment assumption

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Fix pticlonepgtable alignment assumption Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then DF from the stack guard. It turned out that...

kernel: x86/lib: Revert to _ASM_EXTABLE_UA() for {get,put}_user() fixups

In the Linux kernel, the following vulnerability has been resolved: x86/lib: Revert to ASMEXTABLEUA for get,putuser fixups During memory error injection test on kernels = v6.4, the kernel panics like below. However, this issue couldn't be reproduced on kernels getusernocheck4+0x6/0x20 mce: Hardwa...
