CVE-2025-38359

CVE-2025-38359 affects the Linux kernel on s390/x architectures. The issue is a fix in in_atomic() handling in do_secure_storage_access() where kernel user-space accesses to not-exported pages in atomic context can trigger a page fault handling path. The described impact involves a potential slee...

CVE-2025-38359 s390/mm: Fix in_atomic() handling in do_secure_storage_access()

In the Linux kernel, the following vulnerability has been resolved: s390/mm: Fix inatomic handling in dosecurestorageaccess Kernel user spaces accesses to not exported pages in atomic context incorrectly try to resolve the page fault. With debug options enabled call traces like this can be seen:...

CVE-2022-49214

CVE-2022-49214 pertains to the Linux kernel on PowerPC 64s where Data SLB (Data Segment) faults do not set DSISR to a useful value, causing misclassification of read vs. write faults. The fix reworks the printing logic to treat SLB faults separately and only print read/write when the fault type c...

In the Linux kernel, the following vulnerability has been resolved: s390/stacktrace: Use break instead of return statement archstackwalkusercommon contains a return statement instead of a break statement in case storeip fails while trying to store a callchain entry of a user space process. This m...

SUSE CVE-2015-8839

Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local users to cause a denial of service disk corruption by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling...

Linux 5.6 IORING_OP_MADVISE Race Condition

Linux 5.6 has an issue with IORINGOPMADVISE racing with coredumping. Linux 5.6: IORINGOPMADVISE races with coredumping Last year, I noticed that core dumping iterates over current-mm's VMA list without proper locking, under the assumption that the VMA list can not be modified externally. This...

Kernel: KVM: leak of uninitialized stack contents to guest

An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructions like VMXON, VMCLEAR, VMPTRLD, and VMWRITE with memory address as an operand. It occurs if the operand is a mmio address, as the returned exception object hold...
