kernel: fscache: Fix invalidation/lookup race

In the Linux kernel, the following vulnerability has been resolved: fscache: Fix invalidation/lookup race If an NFS file is opened for writing and closed, fscacheinvalidate will be asked to invalidate the file - however, if the cookie is in the LOOKINGUP state or the CREATING state, then request ...

kernel: nfsd: Fix a memory leak in an error handling path

In the Linux kernel, the following vulnerability has been resolved: nfsd: Fix a memory leak in an error handling path If this memdupuser call fails, the memory allocated in a previous call a few lines above should be freed. Otherwise it leaks...

kernel: NFS: Avoid writeback threads getting stuck in mempool_alloc()

In the Linux kernel, the following vulnerability has been resolved: NFS: Avoid writeback threads getting stuck in mempoolalloc In a low memory situation, allow the NFS writeback code to fail without getting stuck in infinite loops in mempoolalloc...

kernel: NFSD: Fix potential use-after-free in nfsd_file_put()

In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix potential use-after-free in nfsdfileput nfsdfileputnoref can free @nf, so don't dereference @nf immediately upon return from nfsdfileputnoref...

kernel: nfsd: don't replace page in rq_pages if it's a continuation of last page

In the Linux kernel, the following vulnerability has been resolved: nfsd: don't replace page in rqpages if it's a continuation of last page The splice read calls nfsdspliceactor to put the pages containing file data into the svcrqst-rqpages array. It's possible however to get a splice result that...

kernel: NFSD: Protect against send buffer overflow in NFSv2 READ

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READ Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. This...

kernel: NFSD: Finish converting the NFSv2 GETACL result encoder

A flaw was identified in the Linux kernel’s NFSD NFSv2 GETACL result encoder. During conversion to xdrstream, leftover code erroneously set the pagelen field of the send buffer. The XDR stream encoders are expected to manage buffer length automatically, and the incorrect manual setting can result...

kernel: NFS: Fix an Oops in nfs_d_automount()

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix an Oops in nfsdautomount When mounting from a NFSv4 referral, path-dentry can end up being a negative dentry, so derive the struct nfsserver from the dentry itself instead...

kernel: NFSD: Protect against send buffer overflow in NFSv2 READDIR

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READDIR Restore the previous limit on the @count argument to prevent a buffer overflow attack...

kernel: driver core: Fix wait_for_device_probe() & deferred_probe_timeout interaction

In the Linux kernel, the following vulnerability has been resolved: driver core: Fix waitfordeviceprobe & deferredprobetimeout interaction Mounting NFS rootfs was timing out when deferredprobetimeout was non-zero 1. This was because ipautoconfig initcall times out waiting for the network interfac...

kernel: NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN

In the Linux kernel, the following vulnerability has been resolved: NFSv4/pNFS: Fix a race to wake on NFSLAYOUTDRAIN We found a few different systems hung up in writeback waiting on the same page lock, and one task waiting on the NFSLAYOUTDRAIN bit in pnfsupdatelayout, however the pnfslayouthdr's...

kernel: NFSD: Protect against send buffer overflow in NFSv3 READDIR

A buffer management flaw was found in the Linux kernel's NFS server implementation in the NFSv3 READDIR operation handling. A remote client can trigger this issue by crafting an RPC call with an oversized RPC record header, which forces the server to shrink its response buffer allocation. This...

kernel: use-after-free caused by invalid pointer hostname in fs/cifs/connect.c

A use-after-free flaw was found in reconnsetipaddrfromhostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server-hostname to NULL, leading to an invalid pointer request...
