Graphic format mismatch while converting video format in hwcomposer prior to SMR Mar-2021 Release 1 results in kernel panic due to unsupported format.

Samsung devices with Android KK(4.4) or L(5.0/5.1) allow local users to cause a denial of service (IAndroidShm service crash) via crafted data in a service call.

The getURL function in drivers/secfilter/urlparser.c in secfilter in the Samsung kernel for Android on SM-N9005 build N9005XXUGBOB6 (Note 3) and SM-G920F build G920FXXU2COH2 (Galaxy S6) devices allows attackers to trigger a NULL pointer dereference via a "GET HTTP/1.1" request, aka SVE-2016-5036.

Assuming radio permission is gained, missing input validation in modem interface driver prior to SMR Oct-2021 Release 1 results in format string bug leading to kernel panic.

An incorrect implementation handling file descriptor in dpu driver prior to SMR Mar-2021 Release 1 results in memory corruption leading to kernel panic.

An improper input validation vulnerability in loading graph file in DSP driver prior to SMR Sep-2021 Release 1 allows attackers to perform permanent denial of service on the device.

The Samsung Exynos fimg2d driver for Android with Exynos 5433, 54xx, or 7420 chipsets allows local users to cause a denial of service (kernel panic) via a crafted ioctl command. The Samsung ID is SVE-2016-6736.

An exploitable integer underflow vulnerability exists in the ZigBee firmware update routine of the hubCore binary of the Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The hubCore process incorrectly handles malformed files existing in its data directory, leading to an infinite loop, which eventually causes the process to crash. An attacker can send an HTTP request to trigger this vulnerability.

Multiple buffer overflows in the esa_write function in /dev/seirenin the Exynos Seiren Audio driver, as used in Samsung S6 Edge, allow local users to cause a denial of service (memory corruption) via a large (1) buffer or (2) size parameter.

Samsung Gallery on the Samsung Galaxy S6 allows local users to cause a denial of service (process crash).

Samsung Gallery in the Samsung Galaxy S6 allows local users to cause a denial of service (process crash).

The memory resource controller (aka memcg) in the Linux kernel allows local users to cause a denial of service (deadlock) by spawning new processes within a memory-constrained cgroup.

In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c.

An issue was discovered in the Linux kernel through 4.17.2. Since the page allocator does not yield CPU resources to the owner of the oom_lock mutex, a local unprivileged user can trivially lock up the system forever by wasting CPU resources from the page allocator (e.g., via concurrent page fault events) when the global OOM killer is invoked. NOTE: the software maintainer has not accepted certain proposed patches, in part because of a viewpoint that "the underlying problem is non-trivial to handle.
