Details of a Linux kernel 0-day vulnerability lurking in Red Hat’s network scheduler have been disclosed, revealing a sophisticated exploit chain that escalates from a limited Use-After-Free (UAF) vulnerability to physical memory read/write access and eventually to privilege escalation.
Linux 7.2 kernel's fourth release candidate, rc4, has been unveiled. Once again, AI/LLMs have contributed to numerous fixes, with Linus Torvalds calling it the "new normal."
Linux 7.2-rc3 has been released, featuring Ultra RISC-V support, Dreamcast driver fixes, and numerous AI-assisted patches. Linus Torvalds hints at a transition to a "new normal." Ubuntu 26.10 will also adopt this kernel.
UltraRISC support has been integrated into Linux 7.2's RISC-V defconfig, targeting the UR-DP1000 SoC (8-core C100), expanding the ecosystem.
AMDGPU driver maintainer Alex Deucher submits 30 patches to replace BUG() macros, which cause kernel panics, with warnings or errors, enhancing stability and security.
Following its deprecation in Linux 7.2, the AF_ALG interface in the Linux kernel will see stricter restrictions in version 7.3 with a new `af_alg_restrict` sysctl parameter, featuring three levels of control to mitigate security risks.
A critical use-after-free vulnerability caused by a race condition has been discovered in the Linux kernel's epoll subsystem. While Anthropic's AI "Mythos" identified a separate bug in the same code area, it failed to detect this vulnerability.
For the first time, an AMD device ID is added to the UFS host controller PCI driver "ufshcd-pci" in the Linux 7.2 kernel, expanding support beyond Intel.
