K26301924: Linux kernel vulnerability CVE-2018-15594

Security Advisory Description arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests. CVE-2018-15594 Impact Traffix SDC When this vulnerability is exploited, an...

SUSE CVE-2018-15594

arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests...

SUSE CVE-2018-15572

The spectrev2selectmitigation function in arch/x86/kernel/cpu/bugs.c in the Linux kernel before 4.18.1 does not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks...

SUSE CVE-2019-9793

A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. This vulnerability could allow an attacker to create an arbitrary value in compiled JavaScript, for which the range analysis will infer a fully...

SUSE CVE-2019-15902

A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream "x86/ptrace: Fix possible spectre-v1 in ptracegetdebugreg" commit reintroduced the...

SUSE CVE-2019-18660

The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry64.S and arch/powerpc/kernel/security.c...

SUSE CVE-2020-10767

A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB Indirect Branch Prediction Barrier. The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation IBRS is available. This flaw allows a loc...

SUSE CVE-2020-10768

A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threa...

SUSE CVE-2020-27171

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error with a resultant integer underflow affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information...

SUSE CVE-2020-27170

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This...

SUSE CVE-2021-29155

An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory. Specifically, for sequences ...

SUSE CVE-2022-23960

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. Then, cache allocation can allow the attacker to obtai...

SUSE CVE-2022-25368

Spectre BHB is a variant of Spectre-v2 in which malicious code uses the shared branch history stored in the CPU BHB to influence mispredicted branches in the victim's hardware context. Speculation caused by these mispredicted branches can then potentially be used to cause cache allocation, which...

SUSE CVE-2022-29901

Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under...
