SUSE CVE-2024-45819

PVH guests have their ACPI tables constructed by the toolstack. The construction involves building the tables in local memory, which are then copied into guest memory. While actually used parts of the local memory are filled in correctly, excess space that is being allocated is left with its prio...

In the Linux kernel, the following vulnerability has been resolved: x86/mce: Work around an erratum on fast string copy instructions A rare kernel panic scenario can happen when the following conditions are met due to an erratum on fast string copy instructions: 1 An uncorrected error. 2 That err...

kernel: x86/mm/pat: fix VM_PAT handling in COW mappings

CVE-2024-35877 pertains to a flaw in the Linux kernel's handling of Page Attribute Table PAT settings during Copy-On-Write COW operations. When a write operation triggers a COW event, the kernel may replace the original page table entries PTEs with anonymous folios. This replacement disrupts the...

kernel: rcu: dump vmalloc memory info safely

A flaw was found in the Read-Copy-Update RCU core of the Linux kernel related to how memory information for vmalloc-allocated objects is dumped. Under certain sequences, calling callrcu may lead to the invocation of vmallocdumpobj while holding the vmaparealock spinlock in an interrupt context...

kernel: cachefiles: defer exposing anon_fd until after copy_to_user() succeeds

A vulnerability was found in the Linux kernel's cachefiles component, regarding the handling of anonymous file descriptors. This issue occurs when an anonymous fd is exposed to userland before confirming the success of the copytouser operation, which can lead to a use-after-free condition...

In the Linux kernel, the following vulnerability has been resolved: drm/shmem-helper: Fix BUGON on mmapPROTWRITE, MAPPRIVATE Lack of check for copy-on-write COW mapping in drmgemshmemmmap allows users to call mmap with PROTWRITE and MAPPRIVATE flag causing a kernel panic due to BUGON in...

kernel: net/sched: fix lockdep splat in qdisc_tree_reduce_backlog()

CVE-2024-35892 is a vulnerability in the Linux kernel’s network scheduler caused by improper use of the qdisclookup function. This function assumes the global RTNL lock is held, but in the qdisctreereducebacklog function, only a local queue lock is used. This mismatch creates a race condition tha...
