FreeBSD -- Multiple vulnerabilities in the sound(4) mmap path

Problem Description: The sound4 driver contained two memory-safety errors in its mmap2 support. First, dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length...

DEBIAN-CVE-2021-42252

An issue was discovered in aspeedlpcctrlmmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs becaus...

kernel: lack of check for mmap minimum address in expand_downwards in mm/mmap.c leads to NULL pointer dereferences exploit on non-SMAP platforms

A flaw was found in mmap in the Linux kernel allowing the process to map a null page. This allows attackers to abuse this mechanism to turn null pointer dereferences into workable exploits...

USN-3007-1 linux-raspi2 vulnerabilities

Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux kernel incorrectly enables scatter/gather I/O. A remote attacker could use this to obtain potentially sensitive information from kernel memory. CVE-2016-2117 Jann Horn discovered that eCryptfs improperly attempted to use...

security flaw

The mmap function in the Linux Kernel 2.6.10 can be used to create memory maps with a start address beyond the end address, which allows local users to cause a denial of service kernel crash...
