FKIE_CVE-2021-33200
Vulnerability from fkie_nvd - Published: 2021-05-27 13:15 - Updated: 2024-11-21 06:08
Severity ?
Summary
kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.

FKIE_CVE-2021-26708
Vulnerability from fkie_nvd - Published: 2021-02-05 14:15 - Updated: 2024-11-21 05:56
Severity ?
Summary
A local privilege escalation was discovered in the Linux kernel before 5.10.13. Multiple race conditions in the AF_VSOCK implementation are caused by wrong locking in net/vmw_vsock/af_vsock.c. The race conditions were implicitly introduced in the commits that added VSOCK multi-transport support.

FKIE_CVE-2020-27786
Vulnerability from fkie_nvd - Published: 2020-12-11 05:15 - Updated: 2024-11-21 05:21
Severity ?
Summary
A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

FKIE_CVE-2020-29573
Vulnerability from fkie_nvd - Published: 2020-12-06 00:15 - Updated: 2024-11-21 05:24
Severity ?
Summary
sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference.

FKIE_CVE-2020-25221
Vulnerability from fkie_nvd - Published: 2020-09-10 14:15 - Updated: 2024-11-21 05:17
Severity ?
Summary
get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743.

FKIE_CVE-2020-15852
Vulnerability from fkie_nvd - Published: 2020-07-20 19:15 - Updated: 2024-11-21 05:06
Severity ?
Summary
An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port permissions of an unrelated task. This occurs because tss_invalidate_io_bitmap mishandling causes a loss of synchronization between the I/O bitmaps of TSS and Xen, aka CID-cadfad870154.

CVE-2021-33200 (GCVE-0-2021-33200)
Vulnerability from cvelistv5 – Published: 2021-05-27 00:00 – Updated: 2024-08-03 23:42
VLAI?
Summary
kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.
Severity ?
No CVSS data available.

CVE-2020-27786 (GCVE-0-2020-27786)
Vulnerability from cvelistv5 – Published: 2020-12-11 04:05 – Updated: 2024-08-04 16:25
VLAI?
Summary
A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
Severity ?
No CVSS data available.

CVE-2020-29573 (GCVE-0-2020-29573)
Vulnerability from cvelistv5 – Published: 2020-12-05 23:18 – Updated: 2024-08-04 16:55
VLAI?
Summary
sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference.

CVE-2020-25221 (GCVE-0-2020-25221)
Vulnerability from cvelistv5 – Published: 2020-09-10 13:39 – Updated: 2024-08-04 15:33
VLAI?
Summary
get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743.

CVE-2020-15852 (GCVE-0-2020-15852)
Vulnerability from cvelistv5 – Published: 2020-07-20 18:54 – Updated: 2024-08-04 13:30
VLAI?
Summary
An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port permissions of an unrelated task. This occurs because tss_invalidate_io_bitmap mishandling causes a loss of synchronization between the I/O bitmaps of TSS and Xen, aka CID-cadfad870154.
Severity ?
No CVSS data available.

CVE-2021-33200 (GCVE-0-2021-33200)
Vulnerability from nvd – Published: 2021-05-27 00:00 – Updated: 2024-08-03 23:42
VLAI?
Summary
kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.
Severity ?
No CVSS data available.

CVE-2020-27786 (GCVE-0-2020-27786)
Vulnerability from nvd – Published: 2020-12-11 04:05 – Updated: 2024-08-04 16:25
VLAI?
Summary
A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
Severity ?
No CVSS data available.

CVE-2020-29573 (GCVE-0-2020-29573)
Vulnerability from nvd – Published: 2020-12-05 23:18 – Updated: 2024-08-04 16:55
VLAI?
Summary
sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference.

CVE-2020-25221 (GCVE-0-2020-25221)
Vulnerability from nvd – Published: 2020-09-10 13:39 – Updated: 2024-08-04 15:33
VLAI?
Summary
get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743.

CVE-2020-15852 (GCVE-0-2020-15852)
Vulnerability from nvd – Published: 2020-07-20 18:54 – Updated: 2024-08-04 13:30
VLAI?
Summary
An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port permissions of an unrelated task. This occurs because tss_invalidate_io_bitmap mishandling causes a loss of synchronization between the I/O bitmaps of TSS and Xen, aka CID-cadfad870154.
Severity ?
No CVSS data available.
