kernel: use after free in eventpoll.c may lead to escalation of privilege
A flaw was found in the Linux kernel. A logic error in eventpoll.c can cause a use-after-free, leading to a local escalation of privilege with no additional execution privileges. User interaction is not needed for exploitation. The highest threat from this vulnerability is to confidentiality,...
CVE-2022-0286
A flaw was found in the Linux kernel. A null pointer dereference in bondipsecaddsa may lead to local denial of service...
UBUNTU-CVE-2021-45469
In f2fssetxattr in fs/f2fs/xattr.c in the Linux kernel through 5.15.11, there is an out-of-bounds memory access when an inode has an invalid last xattr entry...
Google Android 安全漏洞
Google Android is a Linux-based open source operating system from Google. Google Android 11 has a security vulnerability that stems from a security flaw in the Pixel Kernel...
kernel: Insufficient validation of user-supplied sizes for the MSG_CRYPTO message type
A flaw was discovered in the cryptographic receive code in the Linux kernel's implementation of transparent interprocess communication. An attacker, with the ability to send TIPC messages to the target, can corrupt memory and escalate privileges on the target system...
kernel: flowtable list del corruption with kernel BUG at lib/list_debug.c:50
A flaw was found in the Linux kernel netfilter implementation. A user with root CAPSYSADMIN access is able to panic the system when issuing netfilter netflow commands...
kernel: Use-after-free in ndb_queue_rq() in drivers/block/nbd.c
A use after free flaw in the Linux kernel network block device NBD subsystem was found in the way user calls an ioctl NBDSETSOCK at a certain point during device setup...
kernel: Intel graphics card information leak.
An information disclosure flaw was found in the Linux kernel. The i915 graphics driver lacks control of flow for data structures which may allow a local, authenticated user to disclose information when using ioctl commands with an attached i915 device. The highest threat from this vulnerability i...
kernel: heap overflow in __cgroup_bpf_run_filter_getsockopt()
A flaw buffer overflow in the Linux kernel BPF subsystem was found in the way user running BPF script calling getsockopt. A local user could use this flaw to crash the system or possibly escalate their privileges on the system...
kernel: System crash in intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c
A flaw was found in the Linux kernel. On some Haswell CPUs, userspace applications such as perf-fuzzer can cause a system crash because the PEBS status in a PEBS record is mishandled...
kernel: Improper input validation in the Intel(R) Ethernet ixgbe driver may allow an authenticated user to potentially enable DoS via local access
A flaw was found in the Linux kernel. This flaw allows an attacker who can modify the MTU of a virtualized PCIe device in a guest, for example to crash the host system’s kernel if they set the MTU of the VF device to an unsupported value...
kernel: buffer overflow in mwifiex_cmd_802_11_ad_hoc_start function in drivers/net/wireless/marvell/mwifiex/join.c via a long SSID value
A flaw was found in the Linux kernel. The marvell wifi driver could allow a local attacker to execute arbitrary code via a long SSID value in mwifiexcmd80211adhocstart function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...
kernel: System crash in intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c
A flaw was found in the Linux kernel. On some Haswell CPUs, userspace applications such as perf-fuzzer can cause a system crash because the PEBS status in a PEBS record is mishandled...
kernel: out-of-bounds write due to a heap buffer overflow in __hidinput_change_resolution_multipliers() of hid-input.c
A flaw out of bounds memory write in the Linux kernel HID subsystem was found in the way user attach USB or other HID device that generates incorrect data inside HID report field. A local user could use this flaw to crash the system or possibly escalate their privileges on the system...
CVE-2021-43056
An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3shvrmhandlers.S implementation bug in the handling of the SRR1 register values...
kernel: SVM nested virtualization issue in KVM (AVIC support)
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "intctl" field, this issue could allow a malicious ...
Vulnerabilities fixed in Google Android
Google has fixed vulnerabilities in the Android OS. A malicious party can misuse the vulnerabilities to execute arbitrary code execute arbitrary code, gain access to sensitive data or to give themselves elevated privileges. To do this, the malicious party must trick the victim into installing a...
CVE-2021-20317
A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the timerqueueadd function in lib/timerqueue.c. This flaw allows a local attacker with special user privileges to cause a denial of service, slowing and eventually stopping the system while runnin...
