USN-3127-1 linux vulnerabilities

It was discovered that the compression handling code in the Advanced Linux Sound Architecture ALSA subsystem in the Linux kernel did not properly check for an integer overflow. A local attacker could use this to cause a denial of service system crash. CVE-2014-9904 Kirill A. Shutemov discovered...

kernel: Stack overflow via ecryptfs and /proc/$pid/environ

It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to...

Linux kernel local denial of service vulnerability (CNVD-2016-09457)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A denial of service vulnerability exists in the 'prockeysshow' function in the security/keys/proc.c file in Linux kernel versions 4.8.2 and earlier, which stems from a program...

CVE-2016-7042

It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks...
