kernel: powerpc/64s: Don't use DSISR for SLB faults

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Don't use DSISR for SLB faults Since commit 46ddcb3950a2 "powerpc/mm: Show if a bad page fault on data is read or write." we use pagefaultiswriteregs-dsisr in badpagefault to determine if the fault is for a read or...

SUSE CVE-2021-44879

In gcdatasegment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a movedatapage NULL pointer dereference...

The vulnerability of the gc_data_segment function (fs/f2fs/gc.c) in the Linux operating system kernel allows a hacker to trigger a service failure.

The vulnerability of the gcdatasegment function fs/f2fs/gc.c in the Linux operating system kernel is related to pointer arithmetic errors. Exploiting this vulnerability can allow an attacker to cause a service failure...

Linux kernel 代码问题漏洞

Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A code issue vulnerability exists in the Linux kernel that stems from a failure to consider special files in gcdatasegment in Linux kernel fs/f2fs/gc.c prior to 5.16.3, resulting in a null pointer...

CVE-2020-24341

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. The TCP input data processing function in picotcp.c does not validate the length of incoming TCP packets, which leads to an out-of-bounds read when assembling received packets into a data segment, eventually causing Denial-of-Servic...

CVE-2020-6086

An exploitable denial of service vulnerability exists in the ENIP Request Path Data Segment functionality of Allen-Bradley Flex IO 1794-AENT/B. A specially crafted network request can cause a loss of communications with the device resulting in denial-of-service. An attacker can send a malicious...

CVE-2020-6087

CVE-2020-6087 affects Allen-Bradley Flex IO 1794-AENT/B (Series B) via the ENIP Request Path Data Segment. The vulnerability occurs when the ANSI Extended Symbol Segment Sub-Type is used; the following byte is treated as the Data Size in words, and if it exceeds the packet data, the device faults...

CVE-2020-6086

CVE-2020-6086 affects Allen-Bradley Flex IO 1794-AENT/B (EtherNet/IP ENIP) in the ENIP Request Path Data Segment. The issue is triggered when a Simple Data Segment Sub-Type is used: the byte after the segment is treated as the Data Size in words, and if that value exceeds the remaining packet dat...

kernel: load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary

A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as Position Independent Executable PIE, the loader could allow part of that application's data segment to map over the memory area reserved for its stack, potentially resulting in memory...
