CVE-2024-26959

CVE-2024-26959 affects the Linux kernel Bluetooth subsystem (btnxpuart). The issue is a scheduling while atomic BUG in btnxpuart_close that could leave the transmit queue unpurged and skb release unsafe. The fixed path is in btnxpuart_close, with related call chain through tty/serdev/uart during ...

CVE-2024-32984: Uncontrolled Resource Consumption

Yamux is a stream multiplexer over reliable, ordered connections such as TCP/IP. The Rust implementation of the Yamux stream multiplexer uses a vector for pending frames. This vector is not bounded in length. Every time the Yamux protocol requires sending of a new frame, this frame gets appended ...

kernel: tty: n_gsm: add sanity check for gsm->receive in gsm_receive_buf()

In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: add sanity check for gsm-receive in gsmreceivebuf A null pointer dereference can happen when attempting to access the "gsm-receive" function in gsmldreceivebuf. Currently, the code assumes that gsm-recieve is only call...

kernel: HID: hyperv: avoid struct memcpy overrun warning

A compiler warning issue was found in the Linux kernel's Hyper-V HID driver that could lead to potential memory safety issues. A local user can trigger this issue when the fortified memcpy implementation detects potential buffer overflows in the mousevsconreceive function, where the compiler cann...

kernel: io_uring/net: don't overflow multishot recv

A flaw was found in the Linux kernel's iouring subsystem. When using multishot receive operations, completion queue entries CQEs can overflow without proper limits. This can lead to excessive memory consumption, performance degradation, and in worst cases, an out-of-memory OOM condition for the...

Issue Overview: In the Linux kernel, the following vulnerability has been resolved: bpf: Defer the free of inner map when necessary When updating or deleting an inner map in map array or map htab, the map may still be accessed by non-sleepable program or sleepable program. However bpfmapfdputptr...

kernel: use after free in unix_stream_sendpage

A use-after-free flaw was found in the Linux kernel's afunix component that allows local privilege escalation. The unixstreamsendpage function tries to add data to the last skb in the peer's recv queue without locking the queue. This issue leads to a race condition where the unixstreamsendpage...

kernel: veth: ensure skb entering GRO are not cloned.

In the Linux kernel, the following vulnerability has been resolved: veth: ensure skb entering GRO are not cloned. After commit d3256efd8e8b "veth: allow enabling NAPI even without XDP", if GRO is enabled on a veth device and TSO is disabled on the peer device, TCP skbs will go through the NAPI...

kernel: gro: fix ownership transfer

A flaw was found in the Linux kernel's Generic Receive Offload GRO feature, where packets processed with a fragment list are not properly orphaned due to incorrect handling of socket references. This vulnerability can cause system instability or kernel bugs. The issue has been fixed by making sur...
