The Linux kernel has released two new versions, 6.12.55 and 6.6.114, which include important patches aimed at enhancing stability and resolving critical bugs. Noteworthy updates in these versions involve fixes in the mm/ksm module to address flag-dropping behavior during ksm_madvise operations, which previously triggered kernel panics due to inconsistencies with User Fault FD (UFFD). The NFSD module also received patches to prevent crashes during LAYOUTCOMMIT operations on FlexFiles layouts.

Moreover, the PHY module for Cadence D-PHY support has been improved by rectifying bugs related to PLL lock timeout errors during calibration setups. The mptcp module was updated to mitigate potential issues with blackhole periods and interface deregistration, introducing locking mechanisms to safeguard skb->dev access and implementing new helper functions.

Further refinements were made to the arm64 module to tackle challenges with Neoverse-V3AE processors, along with updates to the dmaengine module that streamline module unload operations by adding necessary cleanup calls in the idxd driver’s remove function. These revisions highlight the continuous dedication of developers to maintain a stable, secure, and efficient Linux kernel across diverse hardware configurations.
