CVE-2023-52913

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix potential context UAFs gemcontextregister makes the context visible to userspace, and which point a separate thread can trigger the I915GEMCONTEXTDESTROY ioctl. So we need to ensure that nothing uses the ctx ptr aft...

CVE-2023-52913

CVE-2023-52913 affects the Linux kernel’s drm/i915 component, where gem_context_register() exposes a GEM context to userspace and later code path allows a separate thread to trigger I915_GEM_CONTEXT_DESTROY. The root cause is using the ctx pointer after context destruction and not making the ctx ...

CVE-2021-47517 ethtool: do not perform operations on net devices being unregistered

In the Linux kernel, the following vulnerability has been resolved: ethtool: do not perform operations on net devices being unregistered There is a short period between a net device starts to be unregistered and when it is actually gone. In that time frame ethtool operations could still be...

CVE-2021-47517

CVE-2021-47517 affects the Linux kernel’s ethtool handling: during net-device unregistration a reference to the device can be used, enabling operations after unregister begins. The fix moves the operation into an rtnl-locked path on the netlink side so the net device won’t be found post-unregiste...

curl: Race condition with CURL_LOCK_DATA_CONNECT can cause connections to be used at the same time

Summary: We've seen race conditions when using CURLLOCKDATACONNECT in libcurl where sometimes two different threads using two different easy handles ends up sharing the same connection pointer at the same time. This causes UAFs and double frees when both threads are freeing items on the same...
