An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event, down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and down(&fepriv->sem) may block the process.

An issue was discovered in drivers/tty/n_gsm.c in the Linux kernel 6.2. There is a sleeping function called from an invalid context in gsmld_write, which will block the kernel.

An issue was discovered in drivers/media/test-drivers/vidtv/vidtv_bridge.c in the Linux kernel 6.2. There is a NULL pointer dereference in vidtv_mux_stop_thread. In vidtv_stop_streaming, after dvb->mux=NULL occurs, it executes vidtv_mux_stop_thread(dvb->mux).

NVIDIA DGX-2 SBIOS contains a vulnerability where an attacker may modify the ServerSetup NVRAM variable at runtime by executing privileged code. A successful exploit of this vulnerability may lead to denial of service.

NVIDIA DGX-1 SBIOS contains a vulnerability in Bds, which may lead to code execution, denial of service, and escalation of privileges.

Gipsy is a multi-purpose discord bot which aim to be as modular and user-friendly as possible. In versions prior to 1.3 users can run command on the host machine with sudoer permission. The `!ping` command when provided with an IP or hostname used to run a bash `ping <IP>` without verification that the IP or hostname was legitimate. This command was executed with root permissions and may lead to arbitrary command injection on the host server. Users are advised to upgrade. There are no known workarounds for this vulnerability.

While Intel is building more hardware protections directly into the chips, enterprises still need a strategy for applying security updates on these components.

io.finnet tss-lib before 2.0.0 can leak the lambda value of a private key via a timing side-channel attack because it relies on Go big.Int, which is not constant time for Cmp, modular exponentiation, or modular inverse. An example leak is in crypto/paillier/paillier.go. (bnb-chain/tss-lib and thorchain/tss are also affected.)
