SUSE CVE-2024-26640

In the Linux kernel, the following vulnerability has been resolved: tcp: add sanity checks to rx zerocopy TCP rx zerocopy intent is to map pages initially allocated from NIC drivers, not pages owned by a fs. This patch adds to canmapfrag these additional checks: - Page must not be a compound one....

kernel: use after free in nvmet_tcp_free_crypto in NVMe

A use-after-free vulnerability was found in drivers/nvme/target/tcp.c in nvmettcpfreecrypto due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead t...

The vulnerability of the `nvmet_tcp_build_pdu_iovec()` function in the `drivers/nvme/target/tcp.c` file of the Linux NVMe kernel driver allows a attacker to cause a service failure.

The vulnerability of the nvmettcpbuildpduiovec function in the drivers/nvme/target/tcp.c file of the Linux NVMe kernel driver is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

UBUNTU-CVE-2021-47010

In the Linux kernel, the following vulnerability has been resolved: net: Only allow init netns to set default tcp cong to a restricted algo tcpsetdefaultcongestioncontrol is netns-safe in that it writes to &net-ipv4.tcpcongestioncontrol, but it also sets ca-flags |= TCPCONGNONRESTRICTED which is...

kernel: NULL pointer dereference in __nvmet_req_complete

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service...

kernel: NULL pointer dereference in nvmet_tcp_execute_request

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service...

gRPC: file descriptor exhaustion leads to denial of service

A flaw was found in gRPC. Lack of error handling in the TCP server in Google's gRPC, starting in version 1.23 on POSIX-compatible platforms for example, Linux, allows an attacker to cause a denial of service by initiating a significant number of connections with the server. Note that gRPC C++,...
