In the Linux kernel, the following vulnerability has been resolved: net: do not delay dst_entries_add() in dst_release() dst_entries_add() uses per-cpu data that might be freed at netns dismantle from ip6_route_net_exit() calling dst_entries_destroy() Before ip6_route_net_exit() can be called, we release all the dsts associated with this netns, via calls to dst_release(), which waits an rcu grace period before calling dst_destroy() dst_entries_add() use in dst_destroy() is racy, because dst_entries_destroy() could have been called already. Decrementing the number of dsts must happen sooner. Notes: 1) in CONFIG_XFRM case, dst_destroy() can call dst_release_immediate(child), this might also cause UAF if the child does not have DST_NOCOUNT set. IPSEC maintainers might take a look and see how to address this. 2) There is also discussion about removing this count of dst, which might happen in future kernels.

    ethtool: check device is present when getting link settings(CVE-2024-46679)

    In the Linux kernel, the following vulnerability has been resolved:iommu: Return right value in     iommu_sva_bind_device()  iommu_sva_bind_device() should return either a sva bond handle or an ERR_PTR     value in error cases. Existing drivers (idxd and uacce) only check the return value with IS_ERR(). This     could potentially lead to a kernel NULL pointer dereference issue if the function returns NULL instead of     an error pointer.  In reality, this doesn't cause any problems because iommu_sva_bind_device() only     returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA. In this case,     iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will return an error, and the device drivers won't call     iommu_sva_bind_device() at all.(CVE-2024-40945)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (bookworm), these problems have been fixed in     version 6.1.119-1.

    We recommend that you upgrade your linux packages.
