kernel: block: initialize integrity buffer to zero before writing it to media

A flaw was found in the Linux kernel, where it initialized the integrity buffer to zero before writing it to media. Metadata added by biointegrityprep uses plain kmalloc, which leads to random kernel memory being written. Protection Information PI metadata is limited to the app tag not used by...

CVE-2022-25479

Vulnerability in Realtek RtsPer driver for PCIe Card Reader RtsPer.sys before 10.0.22000.21355 and Realtek RtsUer driver for USB Card Reader RtsUer.sys before 10.0.22000.31274 allows for the leakage of kernel memory from both the stack and the heap...

SUSE CVE-2022-48730

In the Linux kernel, the following vulnerability has been resolved: dma-buf: heaps: Fix potential spectre v1 gadget It appears like nr could be a Spectre v1 gadget as it's supplied by a user and used as an array index. Prevent the contents of kernel memory from being leaked to userspace via...

CVE-2023-52751

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix use-after-free in smb2queryinfocompound The following UAF was triggered when running fstests generic/072 with KASAN enabled against Windows Server 2022 and mount options...

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...

CVE-2022-42896

There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2capcore.c's l2capconnect and l2capleconnectreq functions which may allow code execution and leaking kernel memory respectively remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via...

There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2capcore.c's l2capconnect and l2capleconnectreq functions which may allow code execution and leaking kernel memory respectively remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via...

DEBIAN-CVE-2021-4159

A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating som...

DEBIAN-CVE-2022-25375

An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of the size of the RNDISMSGSET command. Attackers can obtain sensitive information from kernel memory...

kernel: protection for sequences of pointer arithmetic operations against speculatively out-of-bounds loads can be bypassed to leak content of kernel memory

A vulnerability was discovered in retrieveptrlimit in kernel/bpf/verifier.c in the Linux kernel mechanism to mitigate speculatively out-of-bounds loads Spectre mitigation. In this flaw a local, special user privileged CAPSYSADMIN BPF program running on affected systems may bypass the protection,...
