Security Advisory Description CVE-2014-8160 net/netfilter/nfconntrackprotogeneric.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended...
kernel: stack overflow in do_proc_dointvec and proc_skip_spaces
A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system...
Slackware Linux 15.0 kernel-generic Multiple Vulnerabilities (SSA:2023-048-01)
The version of kernel-generic installed on the remote host is prior to 5.15.94 / 5.15.94smp. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-048-01 advisory. - A flaw was found in the KVM's AMD nested virtualization SVM. A malicious L1 guest could purposely fa...
USN-5879-1 linux-hwe-5.19 vulnerabilities
Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service system crash or execute arbitrary code. CVE-2022-4378 Tamás Koczka discovered that the Bluetooth L2CAP handshake...
USN-5877-1 linux-gke-5.15 vulnerabilities
Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service system crash or execute arbitrary code. CVE-2022-4378 Tamás Koczka discovered that the Bluetooth L2CAP handshake...
SUSE CVE-2005-2709
The sysctl functionality sysctl.c in Linux kernel before 2.6.14.1 allows local users to cause a denial of service kernel oops and possibly execute code by opening an interface file in /proc/sys/net/ipv4/conf/, waiting until the interface is unregistered, then obtaining and modifying function...
SUSE CVE-2005-4618
Buffer overflow in sysctl in the Linux Kernel 2.6 before 2.6.15 allows local users to corrupt user memory and possibly cause a denial of service via a long string, which causes sysctl to write a zero byte outside the buffer. NOTE: since the sysctl is called from a userland program that provides t...
SUSE CVE-2011-4080
The sysrqsysctlhandler function in kernel/sysctl.c in the Linux kernel before 2.6.39 does not require the CAPSYSADMIN capability to modify the dmesgrestrict value, which allows local users to bypass intended access restrictions and read the kernel ring buffer by leveraging root privileges, as...
SUSE CVE-2015-2042
net/rds/sysctl.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry...
SUSE CVE-2015-2041
net/llc/sysctlnetllc.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry...
SUSE CVE-2019-9815
If hyperthreading is not disabled, a timing attack vulnerability exists, similar to previous Spectre attacks. Apple has shipped macOS 10.14.5 with an option to disable hyperthreading in applications running untrusted code in a thread through a new sysctl. Firefox now makes use of it on the main...
SUSE CVE-2019-20054
In the Linux kernel before 5.0.6, there is a NULL pointer dereference in dropsysctltable in fs/proc/procsysctl.c, related to putlinks, aka CID-23da9588037e...
SUSE CVE-2020-25285
A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812...
SUSE CVE-2022-0532
An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace...
SUSE CVE-2022-4378
A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system...

CVE-2022-3534
A use-after-free flaw was found in btfdumpnamedups in tools/lib/bpf/btfdump.c in libbpf in the Linux Kernel. This issue occurs because the key stored in the hash table namemap is a string address, and the string memory is allocated by realloc function. When the memory is resized by realloc later,...
