AZL-67752 CVE-2024-35939 affecting package kernel 5.15.200.1-1
In the Linux kernel, the following vulnerability has been resolved: dma-direct: Leak pages on dmasetdecrypted failure On TDX it is possible for the untrusted host to cause setmemoryencrypted or setmemorydecrypted to fail such that an error is returned and the resulting memory is shared. Callers...

CVE-2024-35939
CVE-2024-35939 : The Linux kernel vulnerability in the dma-direct path leaks pages on dma_set_decrypted() failure, allowing a local attacker to cause a denial of service by leaking memory rather than freeing it. Affected component: dma-direct in the Linux kernel (TDX context noted). Conditions: a...
PT-2024-26790
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the dma-direct feature in the Linux kernel, where an untrusted host on TDX can cause set memory encrypted or set memory decrypted to fail, resulting in shared...
PT-2024-27204
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.37 Description The issue arises in CoCo VMs where an untrusted host can cause set memory encrypted or set memory decrypted to fail, leading to shared memory. Callers must handle these errors to prevent...

SUSE CVE-2016-10723
An issue was discovered in the Linux kernel through 4.17.2. Since the page allocator does not yield CPU resources to the owner of the oomlock mutex, a local unprivileged user can trivially lock up the system forever by wasting CPU resources from the page allocator e.g., via concurrent page fault...
kernel: TLB flush happens too late on mremap
Since Linux kernel version 3.2, the mremap syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate removes entries from the pagetables of a task that is in the middle of mremap, a stale TLB entry can remain for a short time that permits access to a physical pag...

Unspecified vulnerability in Linux kernel (CNVD-2018-16689)
Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in Linux kernel versions 4.17.2 and earlier, which stems from the page allocator not providing CPU resources to the oomlock mutex lock...

CVE-2016-10723
CVE-2016-10723 affects the Linux kernel up to version 4.17.2. The issue is in the page allocator: it does not yield CPU resources to the owner of the oom_lock mutex, allowing a local unprivileged user to trap the system in a busy loop by wasting CPU time during oom-killer invocation. The root cau...

Linux - mincore() Uninitialized Kernel Heap Page Disclosure Exploit
Linux mincore discloses uninitialized kernel heap pages. When walkpagerange is used on a VMHUGETLB VMA, callbacks from the mmwalk structure are only invoked for present pages. However, domincore assumes that it will always get callbacks for all pages in the range passed to walkpagerange, and when...
