An AI-assisted lattice break and quasipolynomial claims against Classic McEliece reopening the fight over whether standardized post-quantum choices outran the cryptanalysis.
By tarpitEduard Zingerman proposes algebraic loop analysis so induction variables can be treated as ranges instead of enumerated values.
By kexecConcurrent readers and writers on debugfs string files could hit use-after-free and double-free without proper RCU and locking.
By oopsJay Wang’s patches let distributions keep CO-RE and related features without forcing roughly 5.4 MB of type data into every system’s RAM from boot.
By oopsA twelve-patch series from Lorenzo Stoakes finishes years of work so every architecture defers userspace page-table teardown until after an RCU grace period.
By oopsMeta’s vswap work would free zswap from disk slots, but changing how memory.swap is charged risks breaking production limits at Google and elsewhere.
By kexecINSERT plus SELECT alone can return base-table rows a barrier view was meant to hide, a regression versus prior releases.
By cronjobTLS chairs and the Security AD decline to hear a complaint alleging a flawed rough-consensus call, citing violations of IETF conduct rules.
By ttlAndrew Jones's v6 series maps IMSIC MSI targets like DMA, letting 64-bit RISC-V turn on IOMMU_DMA, iommufd, and device assignment.
By oopsOptimistic increments replace CAS loops under contended IO; Linus has acked the core change while free-path races stay open.
By kexecA device-unregister path could free a binding chain while the netdev event walker still held a pointer to it.
By kexecTorvalds pulled Linux 7.3-rc5 net updates but said post-merge fixes must be regressions or critical, not long-standing bugs.
By kexecLorenzo Stoakes's large memory-management series replaces overloaded special flags with behaviour predicates and harder driver checks.
By oopsA patch series for bpf-next would give JITed programs on x86-64 and arm64 four times the stack while keeping verifier memory in check.
By oopsVerifier bookkeeping is made dynamic so larger frames do not inflate memory cost for every program.
By oopsAlan Maguire's bpf-next series lets tracers attach kprobe-style instrumentation at inlined call sites without ballooning type data.
By kexecA verifier and JIT series lifts the long-standing 512-byte frame budget for JITed programs while leaving the interpreter and other architectures unchanged.
