kernel: load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary
A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as Position Independent Executable PIE, the loader could allow part of that application's data segment to map over the memory area reserved for its stack, potentially resulting in memory...
The vulnerability of the `megasas_mmio_write` function in the QEMU hardware emulation software allows a hacker to exert unpredictable effects.
The vulnerability of the megasasmmiowrite function in the QEMU hardware emulation software is caused by buffer overflow. Exploiting this vulnerability allows a remote attacker to exert unpredictable effects using unknown vectors...
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...
