kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...

kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 shadow paging mechanism. This use-after-free vulnerability arises from incorrect handling of Guest Frame Numbers GFNs when guest page tables are modified. A local attacker with control over a guest virtual machine could...

kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected role

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM x86 shadow paging mechanism. This vulnerability occurs when a host page directory entry PDE mapping is changed from within the guest, leading to an unexpected role mismatch in shadow paging. This mismatch can cause a...

USN-8620-3: Linux kernel (Intel IoTG) vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

kernel: KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Don't recheck L1 intercepts when completing userspace I/O When completing emulation of instruction that generated a userspace exit for I/O, don't recheck L1 intercepts as KVM has already finished that phase of instructi...

kernel: ipc: limit next_id allocation to the valid ID range

A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...
