USN-6466-1 linux-nvidia-6.2 vulnerabilities

Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel contained a race condition during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service system crash or possibly execute arbitrary code...

iLeakage: New Safari Exploit Impacts Apple iPhones and Macs with A- and M-Series CPUs

A group of academics has devised a novel side-channel attack dubbed iLeakage that exploits a weakness in the A- and M-series CPUs running on Apple iOS, iPadOS, and macOS devices, enabling the extraction of sensitive information from the Safari web browser. "An attacker can induce Safari to render...

Patch…later? Safari iLeakage bug not fixed

Apple has released updates for its phones, Macs, iPads, watches, and TV streaming devices, fixing a bunch of security problems. But amid all that activity, one fix is notably absent—there is nothing to address the vulnerability dubbed iLeakage. iLeakage is a side-channel attack that can force the...
