SUSE-SU-2020:3843-1 Security update for the Linux Kernel (Live Patch 0 for SLE 15 SP2)

This update for the Linux Kernel 5.3.18-22 fixes one issue. The following security issue was fixed: - CVE-2020-29369: Fixed a race condition between certain expand functions and page-table free operations from an munmap call, aka CID-246c320a8cfe bsc1179646...

kernel: perf_event_open() and execve() race in setuid programs allows a data leak

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...

Race condition

A pivotroot race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before 4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a denial of service panic by corrupting a mountpoint reference counter...

UBUNTU-CVE-2020-11884

In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enablesacfuaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur...

Exploit for Race Condition in Canonical Ubuntu_Linux

This is a PoC exploit for CVE-2016-5195, a vulnerability in the Linux kernel that allows an attacker to gain root privileges by exploiting a flaw in the way the kernel handles page-zero writes. The exploit is implemented in C++ and Go, and is designed to work on various Linux distributions,...

kernel: incomplete fix for race condition between mmget_not_zero()/get_task_mm() and core dumping in CVE-2019-11599

The fix for CVE-2019-11599 was not complete. A local user could use this flaw to obtain sensitive information, cause a denial of service, or possibly have other unspecified impacts by triggering a race condition with mmgetnotzero or gettaskmm calls...

kernel: l2tp: Race condition between pppol2tp_session_create() and l2tp_eth_create()

A race condition between pppol2tpsessioncreate and l2tpethcreate in net/l2tp/l2tpnetlink.c was found in the Linux kernel. Calling l2tptunnelfind may result in a new tunnel being created with tunnel id of a previously removed tunnel which wouldn't be protected by the reference counter...

kernel: Race condition in sound system can lead to denial of service

In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service. Due to the nature of the flaw, privilege escalation...
