SUSE CVE-2024-53128
In the Linux kernel, the following vulnerability has been resolved: sched/taskstack: fix objectisonstack for KASAN tagged pointers When CONFIGKASANSWTAGS and CONFIGKASANSTACK are enabled, the objectisonstack function may produce incorrect results due to the presence of tags in the obj pointer,...
Linux kernel 安全漏洞
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from the objectisonstack function of the KASAN marker pointer in the sched/taskstack module that may produce incorrec...
AZL-42901 CVE-2024-38667 affecting package kernel for versions less than 6.6.35.1-4
In the Linux kernel, the following vulnerability has been resolved: riscv: prevent ptregs corruption for secondary idle threads Top of the kernel thread stack should be reserved for ptregs. However this is not the case for the idle threads of the secondary boot harts. Their stacks overlap with...
SUSE CVE-2022-48770
In the Linux kernel, the following vulnerability has been resolved: bpf: Guard against accessing NULL ptregs in bpfgettaskstack taskptregs can return NULL on powerpc for kernel threads. This is then used in bpfgetstack to check for user mode, resulting in a kernel oops. Guard against this by...

CVE-2021-47553
In the Linux kernel, the following vulnerability has been resolved: sched/scs: Reset task stack state in bringupcpu To hot unplug a CPU, the idle task on that CPU calls a few layers of C code before finally leaving the kernel. When KASAN is in use, poisoned shadow is left around for each of the...

CVE-2021-47553 sched/scs: Reset task stack state in bringup_cpu()
In the Linux kernel, the following vulnerability has been resolved: sched/scs: Reset task stack state in bringupcpu To hot unplug a CPU, the idle task on that CPU calls a few layers of C code before finally leaving the kernel. When KASAN is in use, poisoned shadow is left around for each of the...
CVE-2021-47553
The CVE describes a Linux kernel issue (CVE-2021-47553) in the SCS and KASAN shadow stack handling for the idle task during CPU hotplug (bringup_cpu). When a CPU is offline and brought back online, stale KASAN shadow and stale shadow call stack (SCS) state could lead to bogus warnings or leak por...
CVE-2021-47553 sched/scs: Reset task stack state in bringup_cpu()
In the Linux kernel, the following vulnerability has been resolved: sched/scs: Reset task stack state in bringupcpu To hot unplug a CPU, the idle task on that CPU calls a few layers of C code before finally leaving the kernel. When KASAN is in use, poisoned shadow is left around for each of the...
CVE-2023-52796 ipvlan: add ipvlan_route_v6_outbound() helper
In the Linux kernel, the following vulnerability has been resolved: ipvlan: add ipvlanroutev6outbound helper Inspired by syzbot reports using a stack of multiple ipvlan devices. Reduce stack size needed in ipvlanprocessv6outbound by moving the flowi6 struct used for the route lookup in an non...
GSD-2021-1002547 sched/scs: Reset task stack state in bringup_cpu()
sched/scs: Reset task stack state in bringupcpu This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.15.6 by commit...
Information Disclosure
Linux kernel is vulnerable to information disclosure vulnerability. The vulnerability exists in the procpidstack function in fs/proc/base.c in the Linux kernel. Local attackers could obtain kernel task stack contents that may lead to further attacks...
CVE-2018-17972
An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents...
