The vulnerability of the pcpu_embed_first_chunk() function in the Linux operating system allows a hacker to gain unauthorized access to certain information.

The vulnerability of the pcpuembedfirstchunk function in the Linux operating system’s kernel relates to the ability to read data from the dmesg output of the printk"pages / cpu" command. Exploiting this vulnerability can allow an intruder to gain unauthorized access to sensitive information...

Information Disclosure

Linux kernel is vulnerable to information disclosure attacks. An attacker could exploit a flaw in the cpismbushcadd function in drivers/acpi/sbshc.c which allows local users to obtain sensitive address information by reading dmesg data from an SBS HC printk call...

Android - binder Use-After-Free of VMA via race Between reclaim and munmap

Android - binder Use-After-Free of VMA via race Between reclaim and munmap The following bug report solely looks at the situation on the upstream master branch; while from a cursory look, at least the wahoo kernel also looks affected, I have only properly tested this on upstream master. There is ...

Android - binder Use-After-Free of VMA via race Between reclaim and munmap

The following bug report solely looks at the situation on the upstream master branch; while from a cursory look, at least the wahoo kernel also looks affected, I have only properly tested this on upstream master. There is a race condition between the direct reclaim path enters binder through the...

Linux Kernel - VMA Use-After-Free via Buggy vmacache_flush_all() Fastpath Local Privilege Escalation

Linux Kernel - VMA Use-After-Free via Buggy vmacacheflushall Fastpath Local Privilege Escalation Since commit 615d6e8756c8 "mm: per-thread vma caching", first in 3.15, Linux has per-task VMA caches that contain up to four VMA pointers for fast lookup. VMA caches are invalidated by bumping the...

Linux Kernel - VMA Use-After-Free via Buggy vmacache_flush_all() Fastpath Local Privilege Escalation

Since commit 615d6e8756c8 "mm: per-thread vma caching", first in 3.15, Linux has per-task VMA caches that contain up to four VMA pointers for fast lookup. VMA caches are invalidated by bumping the 32-bit per-mm sequence number mm-vmacacheseqnum; when the sequence number wraps, vmacacheflushall...

Linux 4.18 - Arbitrary Kernel Read into dmesg via Missing Address Check in segfault Handler

Exploit for linux platform in category dos / poc There is a missing address check in both showopcodes callers. showopcodes is mostly used by the kernel to print the raw instruction bytes surrounding an instruction that generated an unexpected exception; however, sometimes it is also used to print...
