CVE-2019-3901

A race condition in perfeventopen allows local attackers to leak sensitive data from setuid programs. As no relevant locks in particular the credguardmutex are held during the ptracemayaccess call, it is possible for the specified target task to perform an execve syscall with setuid execution...

CVE-2019-3901

CVE-2019-3901 describes a race condition in perf_event_open() that can leak data from setuid processes. The root cause is that cred_guard_mutex is not held during the ptrace_may_access() check, allowing a target task to execve() with setuid execution before perf_event_alloc() attaches, bypassing ...

Race condition

The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs such as /bin/su because installexeccreds is called too late in loadelfbinary in fs/binfmtelf.c, and thus the ptracemayaccess check has a race condition when reading /proc/pid/stat...

CVE-2019-11191

The Linux kernel through 5.0.7, when CONFIGIA32AOUT is enabled and ia32aout is loaded, allows local users to bypass ASLR on setuid a.out programs if any exist because installexeccreds is called too late in loadaoutbinary in fs/binfmtaout.c, and thus the ptracemayaccess check has a race condition...

CVE-2019-11191

The CVE-2019-11191 entry describes a local ASLR bypass in the Linux kernel (up to 5.0.7) when CONFIG_IA32_AOUT is enabled and ia32_aout is loaded. The vulnerability arises because install_exec_creds() is invoked too late in load_aout_binary() (fs/binfmt_aout.c), creating a race in ptrace_may_acce...
