Astra Linux - уязвимость в linux-5.10, linux, linux-5.15, linux-6.1

An integer overflow flaw was discovered in the Linux kernel. This issue causes the kernel to allocate skbsharedinfo in the user space, which can be exploited in systems without SMAP protection, as skbsharedinfo contains references to function pointers...

CVE-2021-29628

In FreeBSD 13.0-STABLE before n245764-876ffe28796c, 12.2-STABLE before r369857, 13.0-RELEASE before p1, and 12.2-RELEASE before p7, a system call triggering a fault could cause SMAP protections to be disabled for the duration of the system call. This weakness could be combined with other kernel...

Enable Kernel SMAP

Supervisor Mode Access Prevention SMAP can be enabled to prevent the kernel from accessing data in user space. If SMAP is not enabled, attackers can access data in user space through kernel-mode code redirection, which increases the attack surface and reduces system security. SMAP is enabled by...

New Linux Kernel Exploit Technique 'SLUBStick' Discovered by Researchers

Cybersecurity researchers have shed light on a novel Linux kernel exploitation technique dubbed SLUBStick that could be exploited to elevate a limited heap vulnerability to an arbitrary memory read-and-write primitive. "Initially, it exploits a timing side-channel of the allocator to perform a...

CVE-2021-47566

CVE-2021-47566 involves a Linux kernel vulnerability in proc/vmcore where user-space buffers were cleared improperly (memset) instead of using clear_user(), enabling a supervisor write fault on a vmcore copy scenario. The fix = use clear_user() when handling user buffers; SMAP handling is noted i...
