CVE-2023-53229

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix invalid drv_sta_pre_rcu_remove calls for non-uploaded sta Avoid potential data corruption issues caused by uninitialized driver private data structures.

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

mmc: vub300: fix return value check of mmc_add_host()

mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path.

So fix this by checking the return value and goto error path which will call mmc_free_host(), besides, the timer added before mmc_add_host() needs be del.

And this patch fixes another missing call mmc_free_host() if usb_control_msg() fails.(CVE-2022-50251)

In the Linux kernel, the following vulnerability has been resolved:

PNP: fix name memory leak in pnp_alloc_dev()

After commit 1fa5ae857bb1 ("driver core: get rid of struct device's bus_id string array"), the name of device is allocated dynamically, move dev_set_name() after pnp_add_id() to avoid memory leak.(CVE-2022-50278)

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.(CVE-2022-50290)

In the Linux kernel, the following vulnerability has been resolved:

mmc: rtsx_usb_sdmmc: fix return value check of mmc_add_host()

mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path.

So fix this by checking the return value and calling mmc_free_host() in the error path, besides, led_classdev_unregister() and pm_runtime_disable() also need be called.(CVE-2022-50347)

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: L2CAP: Fix user-after-free

This uses l2cap_chan_hold_unless_zero() after calling __l2cap_get_chan_blah() to prevent the following trace:

Bluetooth: l2cap_core.c:static void l2cap_chan_destroy(struct kref *kref) Bluetooth: chan 0000000023c4974d Bluetooth: parent 00000000ae861c08

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 works because there are no cases where an operation needs a large RPC Call message and a large RPC Reply at the same time.

Once an RPC Call has been received, svc_process() updates svc_rqst::rq_res to describe the part of rq_pages that can be used for constructing the Reply. This means that the send buffer (rq_res) shrinks when the received RPC record containing the RPC Call is large.

A client can force this shrinkage on TCP by sending a correctly- formed RPC Call header contained in an RPC record that is excessively large. The full maximum payload size cannot be constructed in that case.(CVE-2022-50410)

In the Linux kernel, the following vulnerability has been resolved:

scsi: fcoe: Fix transport not deattached when fcoe_if_init() fails

fcoe_init() calls fcoe_transport_attach(&fcoe_sw_transport), but when fcoe_if_init() fails, &fcoe_sw_transport is not detached and leaves freed &fcoe_sw_transport on fcoe_transports list. This causes panic when reinserting module.

BUG: unable to handle page fault for address: fffffbfff82e2213 RIP: 0010:fcoe_transport_attach+0xe1/0x230 [libfcoe] Call Trace: <TASK> do_one_initcall+0xd0/0x4e0 load_module+0x5eee/0x7210 ...(CVE-2022-50414)
