Design/Logic Flaw

When a control related to codec is issued from userspace in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, the type casting is done to the container structure instead of the codec's individual structure, resulting in a device restart after kernel crash occurs...

CVE-2016-5862

CVE-2016-5862 affects Qualcomm-based Android for MSM codecs; the vulnerability arises when a codec control issued from userspace is cast to the container structure rather than the codec’s own structure. This type confusion can lead to a kernel crash and a subsequent device restart on affected Qua...

kernel: race condition between direct and memory-mapped I/O in fs/xfs/xfs_aops.c

It was found that the Linux kernel can hit a BUGON statement in the xfsgetblocks in the fs/xfs/xfsaops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUGON instead of an I/O failure. This allows a local unprivileged attacke...

kernel: Kernel crash by spawning mcrypt(alg) with incompatible algorithm

Algorithms not compatible with mcryptd could be spawned by mcryptd with a direct cryptoalloctfm invocation using a "mcryptdalg" name construct. This causes mcryptd to crash the kernel if an arbitrary "alg" is incompatible and not intended to be used with mcryptd...

kernel: Double free in the inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c

The inetcskclonelock function in net/ipv4/inetconnectionsock.c in the Linux kernel allows attackers to cause a denial of service double free or possibly have unspecified other impact by leveraging use of the accept system call. An unprivileged local user could use this flaw to induce kernel memor...

kernel: nfsd: Incorrect handling of long RPC replies

The NFS2/3 RPC client could send long arguments to the NFS server. These encoded arguments are stored in an array of memory pages, and accessed using pointer variables. Arbitrarily long arguments could make these pointers point outside the array and cause an out-of-bounds memory access. A remote...
